Internal routing problem - 877W

coruna_74
Level 1
Level 1

I'm trying to configure in a 877W a connection to a DSL. With the configuration below, I can ping from the router any Internet address but from any PC on the network I can't. Can somebody tell me what is wrong?

Can you remove "ip nat outside" from the ATM0 interface config and add "ip nat outside" under the Dialer0 interface and then retest.

Jon

Now I can ping Internet addresses from computers inside the network and I can also open connections to ftp servers, but I cannot open web sites through the IE. Any idea?

I have made a few changes in the configuration, and now I've got new problems.

With the conf below the Internet access through LAN goes real slow and the WLAN does not even appear at the computers availables WLANs list.

Any suggestion?
