Hi, I've migrated from cisco 1721 to 1841. This router has 2 adsl wics(1wic 1hwic) and one lan interface with 2 lan addess configured. Behind the router is a firewall. See the attached file. This firewall enables a tunnel, because of this there is no vpn config into the router. This config ran fine into with 1721 but this 1841 has the latest IOS which has a new ios firewall. I think there is a problem with the rules. Remote ips are: access-list 117 permit ip host 217.204.95.134 any access-list 117 permit ip host 82.110.62.66 any access-list 117 permit ip host 217.204.95.135 any And the outside interface: interface ATM0/1/0.1 point-to-point Best regards ...
