    Earlier this month I posted a problem getting RDP to work through our
    VPN tunnel. We have a PIX in out data center that we use the Cisco
    client to connect up to then we use MS RDP to connect to our servers.
    This works just fine when we are on the outside of our new office PIX.
    When we hook up a computer directly to roadrunner on the outside of our
    PIX, this works. When we hookup the same computer on the inside of our
    network, the VPN client connects just fine, but the RDP fails to see any
    of the servers on the other side of the tunnel. Someone ask me top post
    our config. I finally got it. I have hidden our company name, passwords
    and out external IP addresses. If our external IP was 1.2.3.10 I labeled
    it as Our.External.IP.10. I did this as we have multiple external IP
    addresses referenced within our config and it will let you see were they
    are referenced. Here is our config. and Thanks for any assistance.

    Notes: Our.Outside.IP.xx hides our 1st 3 octets of our IP address.
