Cisco 851 not passing DNS to the computers on the LAN

by krueger_alex . Updated 17 years, 10 months ago

I’ve got a Cisco 851 that is working as I like, mostly. It’s been a trip getting it to work, as this is my first non-consumer grade router!
The last issue is that it won’t act as a DNS server for the computers that are on the LAN (the can’t surf the net). I put the actual DNS server address into the configuration, with these lines:

ip domain name yourdomain.com
ip name-server xxx.xxx.xxx.xxx
ip name-server yyy.yyy.yyy.yyy

And then set the computers on the LAN either as DHCP, or static with the DNS address pointing to the IP of my 851. It doesn’t work. What I then try is just to point the computers directly to xxx.xxx.xxx.xxx and yyy.yyy.yyy.yyy and then they can surf the net. What step am I leaving out?
