I am trying to establish VPN connectivity using VPN 5000 client from my office and cisco 2600 router at my central site. But I am not abe to connect when I use NAT on my perimeter router.I also tried giving NAT transparency on the client.
Without NAT, after giving public address to my PC it works fine. It also works fine with other Cisco VPN client(even with NAT) . Can anyone suggest a solution to this problem?
I have configured dynamic map on Cisco2600 at the central site. I have a 1720 router at my remote site and connected to the central site through internet. I am trying to access the private network at the central site from the VPN client at the remote site. As there are more users we cannot provide public address to everyone. So I have configured PAT on the 1720 router. All the users has VPN 5000 client.
It is not working when I configure PAT on the router. But it is working when I test with VPN Client 3.6. I tried enabling NAT transparency on the 5000 client. But no success. But when I give a public address to the PC then I am able to connect with 5000 Client . So I think PAT is causing the problem.
