LAN Configuration

3-5

The feature is particularly useful in Auto Rollover mode. For example, if the DNS servers 
for each connection are different, then a link failure may render the DNS servers 
inaccessible. However, when the DNS proxy is enabled, then clients can make requests to 
the router and the router, in turn, sends those requests to the DNS servers of the active 
connection.

–

When enabled, the router will act as a proxy for all DNS requests and communicate 
with the ISP’s DNS servers (as configured in the WAN settings page).

–

When disabled, all DHCP clients will receive the DNS IP addresses of the ISP.

6. Click Reset to discard any changes and revert to the previous configuration.

If you have computers using different IP networks in the LAN, (for example, 172.16.2.0, 10.0.0.0), 
then you can add aliases to the LAN port and give computers on those networks access to the 
Internet.

The Available Secondary LAN IPs table lists the secondary LAN IP addresses added to the router.

•

IP Address: The IP address alias added to the LAN port of the router. This is the gateway for 
computers that need to access the Internet.

•

Subnet Mask: IPv4 Subnet Mask.

Note: Once you have completed the LAN IP setup, all outbound traffic is allowed 

and all inbound traffic is discarded. To change these traffic rules, refer to
