Migration from cisco 1721 to 1841

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

Hi

Could you draw us a layout of the network, also you've attached the config and not the log, so could you add what error messages you're getting and detail what issues you are having please?

Cheers

Hi,

The router has 2 wic interfaces...with this scenario only the second one.

Scenario->

Wic->router->watchdog firewall(enabled a 3des vpn).

This firewall has an ip address like 10.168.157.x.

The problem is... is impossible to stablish this vpn, no connection from remote sites 217.x.x.x to this firewall.

Hi,

Do not worry!!!

I switched to my old 1721 until the problem will be resolved.

This friday afternoon I'll connect again my 1841 and data will be posted ok?

Best regards
