    Hi,

    I am having a problem that I just can't understand. A vpn tunnel up (using
    Cisco VPN client and a cisco router at the office), and I can ping the server
    (and the server can ping me). I can also web browse to the server (ie
    exchange, sharepoint).

    I cannot connect using the rdp client, it is like it is not giving me access
    to the rdp port.

    Thanks

    Chris

  2. Hello,

    Do you have 1 or two network cards ? If so, are you pinging the server
    on a range that exists internally and is allowed to answer RDP calls ?

    (In the Terminal Services configuration, do you have the RDP service
    asnwering on all network cards or a specific card ?)

    If you run a "Netstat -an" does it show the IP of the server answering
    on 3389 ?

    I hope one of these questions helps you find your answer or at the least
    provide us with more info for your answer.

    thanks

    I have a simple related question... I use RDP from work, to manage my home
    SBS. When I log in to make an RDP connection, is that logon encrypted or am
    I sending a clear txt logon ?

    Do

    Hi Michael,

    Let's see if I can give you lots of information. I know I can connect to
    the server via rdp through a port forward setup on the firewall.

    The server has one network card, and it's ip is 10.1.0.5. I have a cisco
    router that I use as the 'vpn server'. It's ip address is 10.1.0.1. I have
    a port forwarded from the external address of the cisco router (ip 1.2.3.4)
    redirected to 10.1.0.5 on port 3389.

    When I try to rdp to the external address (ie not through a vpn), then I can
    connect to the server. If I vpn onto the cisco router, then I am given an ip
    address 10.2.0.1. With this ip address I am able to 'ping' and 'http' the
    server, but not connect to it via rdp.

    If I was to guess, I would almost say there is some sort of setting to
    exclude it from outside the local network.

    I can't understand this at all.

    Thanks!

    Chris

    Well looky looky... it seems that I just have just found my problem, because
    I had the port forwarding on on the cisco. So I removed the port forwarding,
    and it worked good.

    That's the deal...

    Thanks everyone!
