Vpn Client to 1841

I need your help to solve the following vpn problem:

In the central site I'm using a 1841 router (version 12.4) with dsl connectivity to internet. I attached the script here for the central site.

This site is connected with 3 remote site (router 1801) with a vpn connection and all work very well.

Now I nedd to implement a vpn with a client (windows xp) using client VPN (version 4.6 or 4.8).

The vpn client can establish the VPN link with the 1841 router but I can't ping the fastethernet0/0 interface or any hosts of the remote network.

The same configuration of dynamic VPN works fine with a 837 router version 12.2.

Any ideas, please?

I am waiting your reply.



Re: Vpn Client to 1841

Using IKE, you can configure the Cisco Secure VPN Client to use the public/private key system for encryption. The public/private key system is a method of encrypting and decrypting Internet traffic for a secure connection without prior notification. Public/private key technology uses an encryption algorithm (such as DES) and an encryption key, which two parties---a recipient and a sender---use to pass data between one another. The recipient holds the private key, while the public key belongs to the certification authority (CA) or directory server for distribution
