DNS Relay
The N4100 supports the IPCP (IP Control Protocol) DNS server extensions through
the DNS proxy feature. When this feature is enabled, the N4100 tells the DHCP
clients that it itself is the DNS server. When a computer sends a DNS query to the
N4100, the N4100 acts as a DNS proxy and forwards the query to the real DNS
server learned through IPCP and relays the response back to the computer.

Please note that DNS proxy works only when the ISP uses the IPCP DNS server
extensions. It does not mean you can leave the DNS servers out of the DHCP
setup under all circumstances. If your ISP gives you explicit DNS servers, make
sure that you enter their IP addresses in the DNS server fields.
