replacing a 837 ADSL router by a 1760 ADSL router


My collegue had a 837 running IRB between Eth0/0 and ATM everything was fine. He has deceided to replace it by a 1760 VPN adsl bundle to handle vpn client.

He has just copied/pasted the conf on the new router. But atm0/0 was down/down, I have send him an ADSL crossover cable, and now atm0/0 is up/up. But no traffic is crossing the link.

sh int atm0/0

ATM0/0 is up, line protocol is up
