    I have been looking all day and I can't find the answer to my question.
    I have tried all posts that seem somewhat related but none are exactly
    what i'm doing. And they seem to fail for some reason.

    I have 5 networks I want to network together, but i'm just working on
    getting 2 to work at the moment. Here is my test setup that I can't
    figure out.

    Location 1:
    Cable modem -> Win 2003 server w/ NAT (2 nics) -> 5 computers

    Windows 2003 static ip
    EXTERNAL: (made up, example)
    INTERNAL: (actual)

    Location 2:
    Cable Modem -> Linksys BEFSX42 Router -> 2 computers

    Linksys router
    EXTERNAL: (made up, example)
    INTERNAL: (actual)

    I have IPsec policies configured on the 2003 server, I can establish an
    IPsec connection. However neither sides can see / ping each other.

    I noticed when playing around in routing and remote access when i
    turned it off and back on, just doing VPN with out nat. Changed my
    IPsec policy on router and 2003 server to reflect the change. And it
    sort of worked. I can ping the server, but the server still could not
    ping me. I could access files on the server but I wouldn't show up in
    network neighborhood.

    I'm woundering how do I get this to work, is there a way to get this to
    work? I'm way past deadline on this solution for a customer and i'm
    stuck. My only other idea I had was to disable NAT on the server, setup
    a switch with the server and a router pluged into it, and then plug the
    router into the server as well. So the server would be local to the 5
    computers at location 1 and as well others could VPN into the router.

    Any Idea's. Help please.
