DNS
The Router can be configured to relay DNS settings from your ISP or another available service to workstations on your
LAN. When using DNS relay, the Router will accept DNS requests from hosts on the LAN and forward them to the
ISP’s, or alternative DNS servers. DNS relay can use auto discovery or the DNS IP address can be manually entered by
the user. Alternatively, you may also disable the DNS relay and configure hosts on your LAN to use DNS servers
directly. Most users who are using the Router for DHCP service on the LAN and are using DNS servers on the ISP’s
network, should check Enable Automatic Assigned DNS box.
DNS Configuration window
If you have DNS IP addresses provided by your ISP, enter these IP addresses in the available entry fields for the
Primary DNS Server and the Secondary DNS Server.
