I am trying to set up a simple connection between a Windows 7 machine and a Windows 2008 R2 server using IPSec over a single IP and port. Both machines are on the same LAN. I am testing with a simple TCP tester app where you run a listener on the server and run a sender on the client computer, and you specify the IP and port to send on. It works fine without IPSec or with IPSec set to Allow fallback, or filter set to Permit, but I get no connection once I enable the IPSec with Negotiate security. I am testing over port 9922. Using the Local Security Policy -> IP Security Polices on Local Computer, I set up a policy on each computer, and set them to assigned. I set the IP Filter list with the destination address and port as the server, and any ip or port as the source, mirrored and TCP protocol I set the Filter action to Negotiate security, with integrity and encryption enabled. No tunnel, all Network Conections, and authentication method is preshared key. All firewalls are off, Ike and AuthIP and IPsec policy services are on in both computers. No firewalls are between the computers. When I use a packet sniffer, the Windows7 box does not seem to even be trying to connect once force encrytion is turned on. I can't figure out what I am missing.

Nevermind, It turned out to be the NCP Secure VPN client I had installed messed with something so secure IPSec doesn't work. Even with NCP completely turned off, it doesn't work. I got it working fine from my laptop wihich never had NCP installed.
