Internet browsing and DNS not working on ADSL

Cisco 877 router configured. I can telnet and from the router using the bv as the source interface and it works. The minute I try from the workstation I get problems.

Why is this?

Attached a copy of the ADSL config as well as an output from my workstation

Re: Internet browsing and DNS not working on ADSL

The DNS configured in your DHCP Pool is not reachable or is not working as shown in the error at the workstation. Change the DNS in your DHCP Pool

!

ip dhcp pool test

dns-server ISP_NAME_SERVER_IP_1 ISP_NAME_SERVER_IP_2

However, if you want to use your internal DNS as in your current DHCP Pool configuration, make sure that they are reachable and working. Then, configure your internal DNS to send all recursive queries to your ISP's DNS servers.

Spot on!

THANKS!

The network was not added to my PIX and therefore they couldn't get to the internal DNS server.
