I have set up a Cisco 877W router to connect to our business broadband, however it doesn't give out DNS information to the clients.
A client will get an IP Address from DHCP ok, but doesn't get any DNS information. I would expect that it would get one of the Open DNS server IP Addresses as its DNS server.
I have included the config below.
