TCP/ IP Configuration. QNAP Turbo Station TS-201

3.4 Network Settings

You can configure network settings in this section and enable several powerful applications of TS-201, e.g. Multimedia Station, Download Station, and Web

Server.

3.4.1 TCP/ IP Configuration

You can select one of the following two methods to configure the TCP/IP settings of TS-201.

1. Obtain IP address settings automatically via DHCP

If your network supports DHCP, TS-201 will use DHCP protocol to retrieve the

IP address and related information automatically.

2. Use static IP address

To use fixed IP address for network connection, enter fixed IP address, subnet mask and default gateway.

Primary DNS Server: Enter the IP address of primary DNS server that provides

DNS service for TS-201 in external network.

Secondary DNS Server: Enter the IP address of secondary DNS server that provides DNS service for TS-201 in external network.

Note:

1. Please contact your ISP or network administrator for the IP address of primary and secondary DNS servers. When TS-201 plays the role as a terminal and needs to perform independent connection, e.g. BT download, you must enter at least one DNS server IP for proper URL connection. Otherwise, the function may not work properly.

2. If you select to obtain IP address via DHCP, there is no need to configure the primary and secondary DNS servers. You can enter

“0.0.0.0” in the settings.

Enable DHCP Server

If no DHCP is available in the LAN where TS-201 locates, you can enable this function to enable TS-201 as a DHCP server and allocate dynamic IP address to

DHCP clients in LAN.

You can set the range of IP addresses allocated by DHCP server and the lease time. Lease time refers to time that IP address is leased to the clients by DHCP server. When the time expires, the client has to acquire an IP address again.

For example, to establish a DLNA network, and share the multimedia files on TS-

201 to DLNA DMP via UPnP while there is no NAT gateway that supports DHCP server, you can enable DHCP server of TS-201. TS-201 will allocate dynamic IP address to DMP or other clients automatically and set up a local network.

Note: If there is an existing DHCP server in your LAN, do not enable this function. Otherwise, there will be IP address allocation and network access errors.

Jumbo Frame Settings (MTU)

"Jumbo Frames" refer to Ethernet frames that are larger than 1500 bytes. It is designed to enhance Ethernet networking throughput and reduce the CPU utilization of large file transfers by enabling more efficient larger payloads per packet.

Maximum Transmission Unit (MTU) refers to the size (in bytes) of the largest packet that a given layer of a communications protocol can transmit.

TS-201 uses standard Ethernet frames: 1500 bytes by default. If your network appliances support Jumbo Frame setting, select the appropriate MTU value for your network environment. TS-201 supports 4074 and 7418 bytes for MTU.

Note: Jumbo Frame setting is valid in Gigabit network environment only. Besides, all network appliances connected must enable Jumbo

Frame and use the same MTU value.
