Unable to Establish VPN connection through CheckPoint NG firewall

[RotaryRocket]

At home I have a CheckPoint NG FP3 Firewall connected to my ISP. I am tryigh to establish a VPN connection to work and I keep getting the following error from my VPN (AT&T RAS) software "Error 118-No response from IPSEC terminator during authentication." See timeline below. It works perfectly fine when I use a linksys router to the ISP. I think I need to set IPSEC pass-through on the Firewall. Can anyone help?

What do you FW log say?
Are you allowing the necessary ports/protocols through?

I have allowed in and out everything and it still does not work. When I use my linksys router only with IPSEC pass thru enabled, it works fine. When I use my CP firewall only, which is doing PATing (hide NAT), and open up the firewall to any to any, the VPN still does not work. My thought is that I need to somehow enable IPSEC pass thru on the CP firewall.
