ISA VPN L2TP Fails From Outside

Asked by RPPreacher in MS Internet Security & Accel, Virtual Private Networking (VPN), Cisco PIX Firewall

I had a working PPTP remote access VPN. The VPN server is a Microsoft ISA 2006 Standard box on Windows Server 2003 R2.

I reconfigured the ISA 2006 box to use L2TP, certificates and RADIUS. With a computer on the inside (LAN), this works GREAT; however, if I take that same computer and move it outside the next work. Nothing -- no connection.

We have a PIX 515e (8.03) on the edge; I have opened GRE, ESP, TCP PPTP, UDP ISAKMP, UDP 1701, TCP-UDP 50 -- nothing.

I added to the ACL, permit IP any to the ISA box (temporarily) -- nothing.

Do I need to enable nat-transversal on the PIX?

If so, if I make this during office hours will it muck up our LAN-to-LAN tunnels on the 515e?

Any other ideas?
