I have users who need to run an IPSec VPN from a client through my RedHat Linux-based router, which is  running a Shorewall firewall.  The firewall is doing NAT.  I have a single public IP address.

Linksys routers have an option called "IPSec Passthrough" which I have found  allows this VPN traffic  to pass through.  How can I configure the Shorewall firewall to allow the IPSec traffic to just "pass through?"  I have opened up all the necessary ports, but no luck.

Anyone have experience with this?
