forward port to IP when SBS is the router

    My customer has a DVR (x.x.x.5) that needs 4 different ports forwarded to it
    to view cameras off the Internet. The Internet is connected directly to NIC
    #1 on the SBS2003 server because they use it for a VPN for an out of town
    worker. The SBS's NIC #2 is connected to their LAN where the DVR is.

    Getting the VPN setup was hard enough due to MTU sizes on the out of town
    workers ISP so I don't want to change the setup by running the Internet into
    a VPN router and using its port forwarding instead.

    Does SBS2003 have a way to forward traffic coming in for a port to be
    forwarded to a PC's IP on its network and how do you do it? Is there a netsh
    command or something in the RRAS console?

    The SBS Server is the firewall. I may have found my own answer. I did
    search 1st but found nothing. I kept searching after my post and found this
    but my customer has not tested it yet:

    "If your SBS server is on the edge of the network, and you are using it as
    the gateway, then we will need to configure the port in RRAS (since you have
    standard I am assuming ISA is not in the picture). If you have a router in
    front of SBS, you will also have to allow the port through.

    In SBS, open the Routing and Remote Access MMC from Administrative Tools.
    Expand your server, Ip Routing and select NAT/Basic Firewall. On the right
    panel select your external/network connection and open the properties.
    Go to the Services and Ports tab, click Add, provide a name, select the
    protocol, the incoming port (31), the IP address of the workstation behind
    SBS and the outgoing port (31). Ok the changes.

    This should allow the port to come into the workstation through the SBS

    How do I check the ISA Server version? Is NAT firewalling not enough?

    ISA 2004 is included in SBS 2003 SP1 Premium Edition but you need to
    actually install it. You should know if you've done that. Also look in
    add/remove programs too see if its there.
