VPN client with NAT transversal

[igonzale]

Hi,

My name is Israel Gonzalez from Nextel Mexico. I have a VPN concentrator 3030 in my network. I am traying to establish a VPN with a client with private IP using PAT to reach Internet. I already configure the VPN concentrator and client according with the cisco's configuration example (please see attached file) and it doesn't work. I don't see any packet in the event log of the VPN concentrator and the VPN client on the PC send the following message " connectio terminated by the client, the remote peer is not longer response" I'd like to know if somebody have had the sameissue I have and how i can fiz it.

Thanks

Have you turned NAT-T negotiation on the VPN concentrator? Is there a firewall on your site that is between the VPN concentrator and the Internet? Have the client try to ping the outside ip address of the VPN concentrator. Can you give some more details

I already have turned on the NAT-T negotiation on the VPN concentrator. I don't have a firewall between my VPN concentrator and Internet, It is directly attached to my Internet router and there is not any ACL configuration in the router. Also, the conectivity between the client and the VPN concentrator is fine since he performed some ping tests to the VPN concentrator and it was successful.

Finally, the VPN client was configured to support (NAT/PAT) in the transport tab.

Thanks
