I have a DSL connection over ATM to a Cisco 3620 configured for Integrated
Routing and Bridging. It bridges on the ATM interface and routes to the ISP
on the FastEthernet Interface. Users on the other side of the DSL/ATM cloud
can browse to certain web sites, but most sites are not accessible. The
config of the 3620 is pasted below. I am confident that it is not a DNS
issue because I see the Domain Names being resolved to IP addresses. I am
curious if there is some issue with the routing and bridging that would
cause some traffic to get dropped. I would appreciate any suggestions.
