The LANCOM 1781VA is a professional, high-performance VPN router for high-speed Internet access with integrated VDSL2 and ADSL2+ modem. Thus it provides maximum
flexibility for a transition from ADSL to high-speed VDSL Internet connections. Likewise, an operation without splitter is possible based on ADSL2+ Annex B / J (over ISDN)
or A / M (over POTS). In all industries and branches of trade with high demands on security and performance it is the ideal foundation for a professional site connectivity.
With its extensive VPN capabilities, the device provides secure, high-performance connectivity to branch offices and remote workers. The four ports of the integrated Gigabit
Ethernet switch ensure maximum performance and are also energy-efficient based on IEEE 802.3az: If no data is transmitted over an interface, its power consumption
shuts down automatically. The LANCOM 1781VA supplies everything required of a modern enterprise network, such as comprehensive Quality-of-Service capabilities and
an object-oriented firewall.
More Performance.
The LANCOM 1781VA provides a high-performance platform with hardware NAT for Gigabit-speed during IP packet transmission. As a professional business router, the
device meets with high standards in the areas of network virtualization, security, and VPN networking. With a VPN encryption performance of more than 200 Mbps, remote
sites can be easily connected. At the same time, its computing power, storage capacity, and the high-speed interfaces ensure excellent network performance even at times
of heavy data traffic.
More Security.
The LANCOM 1781VA is ideal for offices or small businesses with high data volumes that want to set up a secure and powerful VPN: The router's VPN gateway supports
five simultaneous IPSec channels, to be upgraded up to 25 channels optionally. Additionally, an object-oriented stateful-inspection firewall protects the network with
intrusion prevention and denial of service protection. Optionally available, the LANCOM Content Filter protects up to 100 users effectively while using the Internet. Flexible
bandwidth management guarantees the availability of all applications (also in local networks) as these can be prioritized with a comprehensive range of Quality-of-Service
More Management.
LCMS, the LANCOM Management System, is a free software package for the LANCOM 1781VA. It enables the configuration of the device, remote maintenance, and
network monitoring. The central component of LCMS, LANconfig, is used to configure the LANCOM 1781VA and other LANCOM devices on the network. The extensive
range of features and the configuration wizards enable a quick setup of the router. LANCOM Large Scale Monitor (LSM) and the free-of-charge LANmonitor offer detailed,
real-time monitoring of parameters, access to log files and statistics, as well as detailed trace-protocol analysis. Other functions in LCMS include the GUI for firewall setup,
automatic backup of configurations and scripts, and the intuitive folder structure with a convenient search function.
More Virtualization.
The LANCOM 1781VA helps you to use your IT resources more effectively and to save costs. The device supports multiple independent networks with the powerful technology
Advanced Routing and Forwarding (ARF). The ARF function on the LANCOM 1781VA provides up to sixteen virtual networks, each with its own settings for DHCP, DNS,
routing, and firewall.
More Reliability for the Future.
With the LANCOM 1781VA corporate networks can be upgraded for the use of the Internet protocol IPv6 using their current infrastructure. Due to the implementation of
dual-stack, the router can be operated in pure IPv4, pure IPv6, or mixed networks. On top of that, several times a year free-of-charge updates for the LANCOM Operating
System (LCOS) are available. Hence, LANCOM offers maximum safeguarding of your investment.

Categories/category profiles
Filter rules can be defined in each profile by collecting category profiles from 58 categories, for example to restrict Internet access to business
purposes only (limiting private use) or by providing protection from content that is harmful to minors or hazardous content (e.g. malware sites).
Clearly structured selection due to the grouping of similar categories. Content for each category can be allowed, blocked, or released by override
Each category can be given an optional manual override that allows the user to access blocked content on a case-by-case basis. The override
operates for a limited time period by blocking the category or domain, or a combination of both. Optional notification of the administrator in case
of overrides
Lists that are manually configured to explicitly allow (whitelist) or block (blacklist) web sites for each profile, independent of the rating server.
Wildcards can be used when defining groups of pages or for filtering sub pages
Timeframes, blacklists, whitelists and categories are collected into profiles that can be activated separately for content-filter actions. A default
profile with standard settings blocks racist, pornographic, criminal, and extremist content as well as anonymous proxies, weapons/military, drugs,
SPAM and malware
Time frames
Timeframes can be flexibly defined for control over filtering depending on the time of day or weekday, e.g. to relax controls during break times for
private surfing
Flexible firewall action
