VPN Client to IOS router with a PIX 515 using PAT in between

We are trying to work out issues on a VPN client configuration the involves VPN client 3.6.3, PIX 515 and a Cisco 2611. PIX is running 6.2 and the router is running IOS 12.2.13T.

The client appears to have connected to the Router via VPN, but cannot complete any transactions. The router always shows 0 byte decrypted. Bytes encrypted are increasing. When the client has Enable Nat Transparency is checked, the connection just sits there when connecting, but when it is unchecked, the connection will establish, but we cannot get to any resources on the protected network. We have a permit ip <router IP address> to any on the PIX. Any one have any ideas or is there anyone who has the same issues? Also, when they use static addresses, it seems to work as well. I am stumped on this one and hope someone has the answer. Thanks Dwane

Hi,

ipsec/udp will work to a router 12.2.13T, and for that make sure that your udp port is opened up on the pix fw, static is working because you have permit ip, and you are connecting w/o NAT transparency.

Thanks
