U General DNS forwarding
All DNS requests that cannot be resolved in another way are forwarded to a 
DNS server. This DNS server is determined according to the following rules:
D Initially the router checks whether a DNS server has been entered in its 
own settings. If it is successful there, it obtains the desired information 
from this server. Up to two higher-level DNS servers can be specified.
D If no DNS server is entered in the router, it will attempt to reach a DNS 
server over a PPP connection (e.g. from the Internet provider) to get the 
IP address assigned to the name from there. This can only succeed if the 
address of a DNS server is sent to the router during PPP negotiation.
D The default route is established and the DNS server searched for there if 
no connection exists.
This procedure does not require you to have any knowledge of the DNS serv-
er address. Entering the Intranet address of your router as the DNS server 
for the workstation computers is sufficient to enable you obtain the name as-
signment. This procedure also automatically updates the address of the DNS 
server. Your local network always receives the most current information even 
if, for example, the provider sending the address changes the name of his 
DNS server or you change to another provider.
