CheckPoint Client not work with Cisco NAT overload router

[universaltelecom]

Hi,

Does anyone know why the CheckPoint VPN client only can establish the VPN tunnel to CheckPoint server through a Cisco 2811 router; but can't access any files at all from the CheckPoint Server?

The Cisco 2811 is a NAT overload router and the CheckPoint Client was behind it.

Any suggestion is much appreciated!

It looks like NAT traversal issue - solution could be enable ISAKMP NAT traversal on VPN server
