Hello all,
I have a little routing problem with an ADSL connection on a Cisco 1721 router. My router connects to the internet properly, I can ping any website from the router itself (eg. ping www.cisco.com works) but my inside users are not able to connect to the Internet. From the router, I can access other routers and ping my ISP. From any station in my LAN I can ping the ATM interface of the router, but I can't ping the ISP or get to the Internet. I set the gateway of the PC to be the FastE0 of the router and I tried putting the DNS as the ISP's DNS or the router itself but it didn't work. Here is my router configuration :-
