Product overview
Functions overview
The RAS- 3G router is designed to
interconnect safely automated devices
over the UMTS 3G or the GPRS-EDGE
service
The connection can be set with devices
connected to the Internet or with devices
connected to a private IP network or
between RAS-3G routers.
VPN can be set between routers to provide
safe and full communication between the
devices connected to the routers.
The product includes an up-to-date serial
to IP gateway, enabling to connect devices
directly to the 3G network and the
Internet.
The RAS-3G is at the same time an IP
router, a VPN client or a VPN server, a
remote access server (RAS) and a stateful
packet inspection firewall.
The RAS-3G is a member of the range
of industrial routers manufactured by
ETIC TELECOM ; that family includes :
•
•
•
•
•
•
an ADSL router
an Intranet router (Ethernet interfaces)
an up to 256 VPNs server rack
a PSTN router
an ISDN router
a PPP RS232 router for particular uses.
That range makes possible to build stateof-the-art remote control systems.
UMTS GPRS EDGE router ref. RAS-3G
User guide ref. 9020009-01
Page 13
PRODUCT OVERVIEW
Due to its functions and its worldwide
3G module, the RAS-3G provides to
authorized users a remote access to
remote industrial devices or industrial
networks around the world through the
3G or GSM-GPRS network.
If the IP address assigned to the RAS-3G
router by the wireless service provider is
not fixed, It is possible to use either the
DynDNS service, or the M2Me_Connect
service provided by ETIC TELECOM.
The M2Me_Connect service makes
possible to set a secure connection
between
• A remote maintenance PC on one
hand,
• and an Ethernet or a serial Machine
network on the other hand through the
Internet.
The M2Me_Connect service is specially
efficient for remote maintenance of
automated systems.
The M2Me_Connect service makes
that connection possible and easy even
if the IP addresses of the PC on one
hand and of the Machine network on
the other hand are private and or
dynamic.

12 Installing the SIM card
Before installing the SIM card into the router, its PIN code must have been cleared.
The PIN code can be cleared using a usual telephone or a smart phone.
Step 1 : Install the SIM card
• Power off the router.
• Remove the anti-steal lid at the top of the product
• Press the SIM card eject button and remove the SIM card drawer.
• Insert the SIM card SIM card drawer.
• Slid the drawer back into the unit and make sure it locks into place.
Step 2 : Check the reception signal strength
•
Switch-on the router
•
The
led first lights red and then green.
•
The
power indicator lights green.
•
The
reception led flashes to indicate cyclically the reception signal strength.
The reception led must flash at least 2 times to ensure a reliable connection.
If the reception led flashes only one time, the reception is poor ; it must be improved otherwise the
connection will be probably not reliable.
If the reception led remains OFF, it means that the 3G service cannot be received at that location or
that the antenna is not correctly connected or is damaged.
•
If the
Page 24
led lights red, it signifies that the PIN code of the SIM card has not been cleared.

Set up steps
To configure the router, we advise to proceed as follows :
•
Connecting a PC to the router
•
Setting up the LAN interface
•
Setting up the WAN interface
•
Setting up the DynDNS service
•
Setting up VPNs
•
Setting up routing and IP address translation functions
•
Setting up address translation and port forwarding
•
Setting up remote users connections and the M2Me_Connect service
•
Setting up the remote users list
•
Setting up the serial gateway or the USB gateway
•
Setting up the firewall
The RAS-3G router is configured with a PC and an HTML browser.
2 DIP switches enable you to set the IP address : Factory address, stored address, BootP or DHCP
client or server.
For the first configuration, we advise to connect the PC directly to the router Ethernet interface.
Modifications can be carried out through the LAN or remotely.

2.1
Connecting a PC to the router for configuration
Overview
Administration server address :
The administration html server is located at the LAN IP address of the router. The default factory address is192.168.0.128.
First setup :
For the first configuration, we advise to connect the PC directly to the LAN interface of the RAS-3G router.
Setup modifications from the LAN or remotely :
Modifications can be carried out
from the LAN interface,
or from the Internet using a port forwarding rule (not advised for security reasons),
or using a remote user connection PPTP, TLS, L2TP/IPSec,
or through a VPN.
Restoring the factory IP address :
The factory IP address of the router on the LAN interface can be restored by setting the DIP switches SW01 ON and SW02
OFF.
In that position of the DIP switches, the stored configuration is not deleted.
Setting the DIP switches in that position gives also a free access to the administration server from the LAN interface.
During operations, the DIP switches must not be left in that position.
Network IP address :
Later in the text, we often speak of “network address”.
We mean the lowest value of the addresses of the network.
For instance, if the netmask of a network is 255.255.255.0, the network address of that network is X.Y.Z.0.
Copy and paste :
Parameters must be entered with the keyboard; they cannot be pasted.
However, it can be useful to paste a string when it is long to avoid errors.
In that case, paste the string, delete the last character of the pasted string, and enter it again with the keyboard.
Saving and restoring the parameters file (see the maintenance chapter)
A parameters file can only be downloaded to a product having the same firmware version. It is why, we advise to assign a
name to a parameter file including the product name and the software version like for instance
“myrouterfile_ras3g1220_V241.bin”.
2.2
First configuration
Step 1 : Check the DIP switches
Coming from factory, the DIP switches SW1 and SW2 are set OFF to select the stored IP address.
Coming from factory, the stored IP address is the factory IP address 192.168.0.128.
Step 2 : Create or modify the PC IP connection.
Assign to the PC an IP @ in accordance with the RAS-3G IP address.
For the first configuration, assign or instance 192.168.0.127 to the PC.
Step 3 : Connect the PC directly to the LAN interface of the RAS-3G router using any Ethernet
cable (straight or cross wired).
Step 4 : Launch the navigator
Enter the LAN IP @ of the router 192.168.0.128.
The Home page of the administration server is displayed

Modifying the configuration from the LAN
If the IP @ of the RAS-3G on the LAN interface is fixed
Step 1 : Ensure the DIP switch SW1 and SW2 are OFF to select the stored IP @.
Step 2 : Launch the html browser and enter the IP address assigned to the router.
Or, launch the ETICFINDER utility to detect the RAS-3G address.
Remark :
If the home page cannot be displayed, refer below.
• If the IP @ of the RAS-3G on the LAN interface is assigned by a DHCP server
Step 1 : Ensure the DIP switch SW1 is OFF and SW2 ON to select DHCP client operation.
Step 2 : Launch ETIC FINDER to detect the RAS-3G address over the LAN interface.
Click the product once detected.

Modifying the configuration remotely
Coming from the factory, the firewall rejects all the IP frames coming from the 3G network.
To modify remotely the configuration, one can use one of the methods described hereafter :
Set a remote user PPTP, TLS, L2TP/IPSec connection towards the antenna iP address of the RAS-3G router.
Connect a PC to the RAS-3G through a VPN set between the RAS-3G t and another router.
Set up a port forwarding rule to authorise IP frames transmitted to the antenna IP address to be
forwarded to the LAN IP address of the RAS-3G router.
If the IP is public but dynamic, one can use the DynDNS service.
In any case, one can use the professional M2Me_Connect service.
3
Rebooting the router after parameters changes
• After the parameters of any page have been completed, click the « Save » button at the bottom of
the page.
• After some parameters changes, the RAS-3G must restart.
When the configuration has been completely carried out, click the « Reboot » red button in the green
bar, when displayed.

Recovering the factory LAN IP address
When launching the html browser, the homepage of the html server may not be displayed; the cause
may be the IP address you entered was wrong.
if the IP address you enter is wrong, you can recover the factory IP address by setting SW01 ON
and SW2 OFF but the configuration of the router is not lost.
The factory IP address 192.168.0.128 will be restored as long as the SW01 and SW02 micro switch
will be left in that position.
Remark : The SW01 and SW02 must not be left in that position during operations.
5
Recovering the factory configuration
If firewall rules have been created finally preventing from reaching any IP address on the LAN
interface including the router itself, it may be necessary to restore the factory configuration of the
router.
To restore the RAS-3G factory configuration,
•
Switch OFF the power supply of RAS-3G router.
•
Press the push button located on the top part of the RAS-3G router under the lid and, switch-on the power supply.

12 Creating VPN connections between routers
12.1
Principles
A VPN tunnel is a safe link set between two end-points routers over an IP network : Both routers
authenticate, data are encrypted and each device of a LAN can exchange data with each device f the
other one.
To get more explanations about how VPNs work, refer to appendix 1.
25 VPNs can be set on the WAN interface of the RAS-3G router.
Two types of VPN can be set : TLS VPN and IPSec VPN.
IPSec has the advantage to be a standard solution.
TLS is easier to employ because the transport layer is TCP or UDP; it is why, it can be easily used
when the VPN must pass through several or even numerous company routers.
Once a type of VPN (TLS or IPSec) has been selected, all the VPN set with the RAS-3G router will be
of the same type.
Two steps are necessary to configure the RAS-3G to create VPN connections between routers :
st
1 step : Select the VPN type and set up the VPN parameters
2 types of VPNs can be used to connect RAS-3G routers together or with other type of routers: IPSec
or TLS/ SSL
Once a type of VPN has be selected, it applies to all the connections with remote routers.
2nd step : Creating VPN connections
A connection can be an incoming connection
or an outgoing connection.
Outgoing
connection
If a connection is an incoming connection,
the local router is named “VPN server” and
the remote router is a “VPN client”.

Configuring the IPSec protocol
•
Select the “Setup” menu, the “network” menu and then ‘VPN connections”.
•
Select the “Ipsec” type of VPN,
•
Click “Properties” .
“ Protocol ” parameter :
AH ((RFC2402) provides integrity, authentication, replay resistance and non-repudiation but not
encryption.
select AH, if no encryption is required or if NAT traversal is required.
ESP provides the same services plus encryption.
If ESP is selected, an encryption and an authentication protocols must be selected.
“Authentication & encryption key” parameters :
Authentication an encryption can be carried-out with a pre-shared key or a certificate.
“Pre-shared key” value :
The pre-shared key value applies to all the connections.
The maximum length of the key is 40 characters.
The same preshared key value will be used for remote users L2TP / IPSec connections.
“Certificate” value
The RAS-3G router is delivered with a certificate stored into the product in our factory.
To add a certificate, refer to the “Security” menu.

“Encryption and hash algorithm phase 1” & “Encryption and hash algorithm phase 2”
parameters :
That parameters allow to define the encryption and hash algorithms in use during the phase 1 of the
exchanges between the end-points (VPN set-up) and during the phase 2 (data exchange).
The default value is Auto; in that case both end-points will negotiate a common algorithm.
“DPD request period” parameters :
A DPD request (also called Keepalive message) is a message sent periodically by each end-point to
the other one to make sure that the VPN must be left active.
This parameters sets the amount of time (in seconds) between two of these requests.
“Connection death time-out” parameters :
This parameter defines the maximum amount of time (in seconds) a VPN connection will stay
established if no traffic or no DPD request message are received from the remote point.
ATTENTION : Once the parameters of the IPSEC connection have been selected, click the OK
button and then the Save button.

RIP protocol
RIP (Routing Information Protocol) is a routing protocol which enables each router belonging to a
network to acquire the routes to any subnet.
The principle is as follows :
Routing table
Each router holds a routing table.
Each entry of the table consists in the destination subnet address and the adjacent router address
leading to that subnet.
Routing table broadcasting :
Each router broadcasts its table.
Routing table update :
Each router updates its own table using the tables received from the other ones.

14 Address and port translation
The RAS-3G provides the capability to replace the original source IP address and the destination
port and IP address in particular situations.
14.1
Port forwarding
Port forwarding consists in transferring the IP frames addressed to the RAS-3G antenna IP address
(WAN IP address) at a particular port number, to a particular device connected to the LAN interface.
The transfer criteria is the port number; the port number is used as an additional address field.
When a frame is addressed to the RAS-3G router with a particular registered port, it is transferred to
a particular device connected to the LAN interface.
Example :
Let us suppose the PC named “W1” connected to the Internet has to send frames to the device PLC1
connected to one Ethernet port of the RAS-3G router.
If a VPn cnnot be set, the solution can be to use the Port forwarding function :
When W1 needs to transmit frames to PLC1, it addresses the frames to the RAS-3G router on a
chosen and agreed port.
The router checks the frame, replaces the destination address by the IP address of the device on the
LAN interface, and eventually changes the port number.

Remark :

Port farwarding is a security defect; it must be used only if the devices conncetd to the LAN interface
of the RAS-3G are themselves protected (password ...) and not dangerous.

Principle
This function is available in RAS-3G-1400, RAS-3G-1201, RAS-3G-1220, RAS-3G-1230 routers only.
That function consists in replacing the source port and IP address or the destination port and IP
address of particular frames received by the router on its interfaces according to configured rules.
It applies to all the frames received by the router on any of its two interfaces except to the IP packets
contained in a remote user PPTP or TLS connection.
It applies as well to frames the destination address of which is the RAS-3G router itself or to frames
the destination IP address is a device belonging to the LAN subnet, or to the WAN subnet or to
another network.
One brings out
the DNAT function which consists in replacing the destination port and IP address.
the SNAT function which consists in replacing the source IP address.
Because the DNAT and SNAT functions modify the IP addresses of the IP packets processed by the
RAS-3G router, and because the firewall filters that frames, it is very important to understand in which
order that different functions are carried out.

15 VRRP redundancy
That function is available only in RAS-3G-1400, RAS-3G-1201, RAS-3G-1220, RAS-3G-1230 routers
15.1
Principle
VRRP is a protocol designed to increase the availability of the default gateway of a subnet.
Thanks to VRRP, a group of two or more routers can service the hosts of one subnet instead of only
one usually; only one router of that group actually routes frames; if it fails another one of the group
takes its place.
The routers belonging to a VRRP group must be connected to the same Ethernet segment.
VRRP works as follows :
An usual IP address is assigned to each router of the group.
An additional and common IP address, called the virtual IP address is assigned to all the routers of the
group. This virtual address is the address which must be stored as the default gateway address in all
the host devices belonging to the subnet.
A priority index is assigned to each router of the group. Using that index, the routers of the group can
elect a master router; the master router is the one which has the greatest priority code. The other
routers are the backup routers.
The master router is the only one to answer to the ARP requests and route actually frames. It uses
the virtual IP address and the virtual MAC address If that option has been selected.
In case of failure of the master router, another master router is elected. It replaces the router in failure.
It will use the same virtual IP address and the virtual MAC address as the previous master router.
The RAS-3G router manages that protocol as well on the LAN and on the WAN interface.

17 Remote users connections
17.1
Principles
A remote user connection is a tunnel set between a remote PC and a router providing the RAS
function (Remote Access Service), like the RAS-3G.
A remote user connection provides security and simplicity advantages :
• The remote user is identified with a login in and password or eventually a certificate.
• The data is encrypted (TLS or L2TP).
• An IP address belonging to the local network is automatically assigned to the remote user’s PC.
The RAS-3G manages PPTP and TLS or L2TP remote connections.
Only one type can be selected. It will apply to all the remote users connections.
A PPTP is the simplest type of remote user connection; data is not encrypted.
The remote user can be identified only with a login and password.
A TLS connection provides encryption; moreover; the remote user can be identified with a log in and
password and with a certificate if necessary.

This function is available in RAS-3G-1400, RAS-3G-1201, RAS-3G-1220, RAS-3G-1230 routers only.
18.1
Overview
The M2Me_Connect service simplifies the connection of a remote PC to a machine through the
Internet.
It provides a solution when a direct PPTP or TLS connection described before shows itself impossible
in particular when the IP address assigned by the provider to the RAS-3G antenna (WAN interface) is
not a public IP address.
The M2Me_Connect service solves that difficulty :
The PC does not connect directly to the RAS-3G; both the PC and the router connect to the
“M2Me_Connect” service.
Once both parties have been authenticated by the M2Me_Connect service with their own certificate, a
TLS VPN is set from end to end from the PC to the RAS-3G router.
The remote user identity is checked by the router to verify he or she belongs to the user list stored in
the RAS-3G router.
Finally, individual access rights are assigned to the remote user depending on his or her identity.

Firewall
Overview
The firewall filters IP packets between the WAN and the LAN interface of the RAS-3G router. It is
divided in 3 particular filters :
•
The remote users filters
The function of the remote users filters is to limit the IP domain an authenticated remote user can
reach when he connects to the RAS-3G router through the Internet.
The remote users filters filter the destination IP address and port number of the IP packets included
inside a PPTP or TLS or L2TP remote user connection.
Thus the IP addresses checked by the remote users filters are LAN IP addresses.
25 remote users filters can be created and assigned individually to each of the users declared in the
user list.
The source IP address of the packets is not checked by the remote users filters because the filters
apply to the remote users connections according the login and password of the remote user checked
when the remote user connection is set.
•
The main filter
It filters IP packets whether carried inside one of the VPNs or outside a VPN.
The main filter checks source and destination IP addresses and the source and destination ports.
The main filter does not check the IP packets included in a remote user connection. That packets are
checked by the remote users filter.
The main filter does not check the IP packets defined in the “Port forwarding” table. That packed are directly forwarded to the
defined device (see Port forwarding).
•
The deny of service filter is made to usual attacks coming from the Internet. That filter
cannot be configured.

Main filter Overview
Main filter structure
For a better organisation, the main filter is divided in two tables; both having the same structure.
The “VPN” filter : It filter the packets transmitted inside the VPNs.
The “WAN” filter : It filters the packets transmitted outside the VPNs
Each of that two filters is made of
a filter policy
and
a filter table each line of which is a filter rule
• Main filter default policy
The default policy is the decision which will be applied if a packet does not match any of the rules of
the filter.
The WAN to LAN and the LAN to WAN traffic are regarded separately because the decision can be
opposite for a packet coming from the WAN or coming from the LAN :
WAN to LAN : The default policy can be “Accept” or “drop”.
LAN to WAN : The default policy can also be “Accept” or “drop”.
For instance, if the default policy assigned the WAN to LAN traffic is “drop”, it means that an IP packet
which does not match any of the rules of the main filter will be rejected.
• Main filter table
The main filter is a table, each line being a rule.
Each rule of the filter is composed a several fields which defines a particular data flow and another
field which is called the action field.
The fields which define the data flow are :

The Action field can take two values
Accept : To authorize the data flow to be forwarded to the router interface.
Drop : To drop the packet which matches the rule.
• How does the main filters works
When the firewall receives a packet, it checks if it matches the first rule..
If it does, the decision is applied to the packet according to the “Action” field.
If it does not, the firewall checks if it matches the second rule; and so on.
If the packet does not match any of the rules of the table, the default policy is applied to the packet (drop or reject).

Configuring the main filter
Select the “Security” menu and then “Firewall” and “Main filter”.
The “Main filter” page is divided in two parts :
WAN traffic rules :
The first part, entitled “WAN” traffic rules, is made to define how the IP packets not carried in a VPN,
have to be filtered.
VPN traffic rules :
The second part, entitled “VPN traffic rules” allows to define how the IP packets carried inside the
VPNs have to be filtered.
Configure successively the WAN traffic rules using the same method.
Step 1 : Select the default policy
“LAN to WAN” parameter :
That parameter sets what the filter will decide if an IP packet coming from the LAN does not match
any f the rules of the filter :
If the value “Accept” is selected, the IP packet will be transmitted to the VPN.
If the value “Drop” is selected, the IP packet will be rejected.
“WAN to LAN” parameter :
That parameter sets what the filter will decide if an IP packet coming from the WAN does not match
any f the rules of the filter :
If the value “Accept” is selected, the IP packet will be transmitted to the LAN.
If the value “Drop” is selected, the IP packet will be rejected.

The cautious default policy is to choose the value “Drop”; at the opposite, if the value “Accept” is
selected, a frame which does not match any of the rules of the filter is transmitted.
Step 2 : Add a rule to the filter
Click the “add a rule” button.
“Direction” parameter :
Select the direction of the data flow to which the rule applies.
“Action” parameter :
Select the value “Accept” if the IP packet has to be transmitted in the selected direction.
Select the value “Drop” if the IP packet has to be rejected.
“Protocol” parameter :
Select the level 3 protocol concerned.
“Source IP address” & “Source port” parameters :
Enter the value of the source IP address and the source port number.
It is possible to enter a range of source IP addresses and not a single IP address by selecting a
netmask value from 1 to 32; It is the number of binary 1 of the netmask; for instance, the value 24
means 255.255.255.0; the value 16 means 255.255.0.0.
”Destination IP address” & “destination port” parameters :
Enter the value of the destination IP address and the destination port number. Select the netmask
value.

Remote users filters
A remote user filter applies to the IP packets received inside a remote user connection.
25 remote user filters can be configured and assigned individually to each of the users declared in the
user list.
A remote user filter is a table of destination port numbers and IP addresses belonging to the LAN
network.
Once a remote user is connected to the RAS-3G router, the router applies the filter assigned to him
(see the remote user form).
According to his identity (Login and password, he will thus only access to the IP domain defined by the
filter.

Overview
The RAW UDP gateway enables you to connect together a group of serial or IP devices through an
IP network.
The group can include IP devices if they have the software pieces able to receive or transmit serial
data inside UDP.
Serial data transmitted by each device is transmitted to all other serial devices through the IP
network.
A table of IP destination gateways is stored in each RAS-3G belonging to the group.
The serial data is encapsulated in the UDP protocol.
The UDP frame is sent to each destination IP address stored in the table.
21.3.2
Configuration
•
Select the “gateway” menu and then the “Transparent” menu and then click “RAW UDP”.
•
Select the “Activate” option.
« Serial input buffer size” parameter (value 1 to 1024) :
Sets the maximum size of an UDP frame.
“End of frame time-out” parameter (value 10 ms to 5 sec ) :
Sets the delay the gateway will wait before sending the UDP frame towards the IP network when no
characters are received from the serial interface.
«UDP port number» parameter :
Sets the UDP port number.
If the Raw UDP gateway is assigned to both serial COM ports, the UDP port numbers must be
different on each port.

22 USB to IP gateway
22.1
Principles
The RAS-3G-1201 provides a USB to IP gateway.
It is able to forward IP traffic from devices connected to the Ethernet network to a USB device.
On the USB interface, the RAS-3G-1201 behaves like a USB host and a PPP client.
The USB device connected to the RAS-3G-1201 USB interface must behave like a PPP server.
Destination IP address; main case
When a device, connected to the Ethernet network, needs to transmit data to the USB device, the
destination address of the IP frames which need to be transmitted to the USB device must be a
specific IP address assigned to the USB gateway of the RAS-3G (see the configuration below).
Destination IP address; Modbus case
If no specific IP address is assigned to the USB gateway (see below), the RAS-3G forwards only
modbus TCP traffic to the USB interface.
The destination IP address of the IP frames must be the LAN IP address of the RAS-3G router.
22.2
Configuration
Select the “Setup” menu and then the “USB” menu.
“Activate” checkbox :
Select the “Activate” checkbox.
“Use a specific IP address” checkbox :
If modbus TCP traffic only has to be forwarded to the USB device, that checkbox must not be
selected.
If other kinds of traffic have to be forwarded, that checkbox has to be selected.
“Specific IP address” parameter :
If modbus TCP traffic only has to be forwarded to the USB interface, no IP address has to be entered.
If other kinds of traffic have to be forwarded to the USB device, an additional IP address must be assigned the
RAS-3G.
That address belongs to the network connected to the LAN interface of the RAS-3G. It is the IP address of the
USB gateway.
It will be used as the destination IP address of the IP frames which must be forwarded to the USB device.
“Accept WAN traffic” checkbox:
It is necessary to select that checkbox it the PC is connected to the network connected to the WAN
interface.
It is not necessary to select that checkbox if the remote PC is connected to the RAS through a VPN.

23 Advanced functions
23.1
Adding a certificate
Coming from the factory, the RAS-3G router includes a certificate delivered by ETIC
TELECOOMUNICATIONS acting as a certification authority.
That certificate can be used to set a VPN between two routers.
Two RAS-3G routers can set a VPN with one another using certificates only if the certificates have
been provided by the same authority.
Additional X509 certificates, provided by ETIC Telecommunications or not, can be downloaded into
the router.
To import a new certificate, the file extension can be PKCS#12 with a password or PEM.
Even if more than one certificate have been downloaded into the RAS-3G router, one certificate can
be used for all the connections.
23.2
23.2.1
Alarms
SNMP
The RAS-3G router is able to send snmp traps when alarms occur.
Activation :
If that option is selected, the router will send an SNMP trap if an alarm is detected.
SNMP network management IP address :
Enter the IP address of the management platform
SysName & SysLocation :
That fields allow to identify the source device.
Example :
Sysname : etic
Syslocation : France
Product start-up :
If that option is selected, the router will send an SNMP trap each time it will connect to the Internet
23.2.2
Digital output alarm
If an alarm occurs, the router will open the digital output..
The causes which make the output to open cane be either the
ADSL disconnection, power input 1 failure, power input 2 failure.
23.2.3
E-mail alarm
When the digital input is closed or opened, an email can be transmitted to one of the users of the
users list.
To set that function select the “Alarm” menu and click “email”.
Enable the alarm email :
Select this option if you want an email to be sent to a user when the digital input 1 is set ON or OFF.

23.3
Configuring the web portal
The web portal in an html page; it displays a list of devices connected to the LAN. Each line of the list
is made of the device name, its IP address and three links :
The html link : To go directly to the web server of the associated machine.
The « explore » link : To explore the HD of the associated machine, if it is a Windows machine.
The « ftp » link : To explore the files of the associated device.
If the we portal option has been selected (see below), the web portal page is displayed when the
remote user launches the navigator and enters the Ip address assigned to the RAS-3G router. In that
case, the administration server, usually can be displayed at the same address but at the port number
8080 instead of 80 when the web portal page option is not selected.

Configuring the DNS server
For domain names resolution, the RAS-3G can behave like a domain name server or a domain name
relay.
DNS server :
A domain name server is a networking device which is able to associate a label (etictelecom.com for
instance) with an IP address.
That function allows a client device to send a request to a network equipment referring to a domain
name as if it was the actual IP address of the destination device.
The RAS-3G router is able to resolve any domain name composed with the name of one of the
devices entered in the devices list followed the site name which is entered at the top of the devices
list.
DNS relay :
The RAS-3G router behaves also like a DNS relay; any DNS request it receives from the LAN, which
cannot be resolved because the device is not registered in the devices list, will be transferred to the
internet to be resolved.
That function can be carried out only if the RAS-3G IP address is pointed out as the main DNS server
of the devices of the LAN.
That function is efficient in particular when a device connected to the LAN has to send emails through
the Internet.
