Hi all,

I want to stablish a vpn between my PC (with VPN Client version 4.8.02.0010) and a remote router (Cisco 2811)with IOS software release 12.4(9)T7 and the following configuration

aaa new-model

!

aaa authentication login VPNCLIENT local

When I connect to the public IP address of the router every thing is all right and status is Connected. But I don't have connectivity to internet and I can only ping 192.168.4.1 but no others IP adress from this range.

I would appreciate any kind of kelp.

Thanks

You need to make sure that your internal traffic going to the VPN client is NOT being NATT'd.

You need to re-write acl 102 to something like:-

access-list 102 deny ip 192.168.4.0 0.0.0.255 192.168.4.0 0.0.0.255

access-list 102 permit ip 192.168.4.0 0.0.0.255 any

Thank you very much. Now it works!

But I'm trying to connect to a PC via remote desktop and I can't. Could you tell me what do I have to add to the router configuration.

Regards
