ISA2004 and RDC to non-standard port

Posted on 2006-04-21

I am on a SBS2003 Server with ISA2004
I can make remote desktop connections from the SBS2003 server to external systems on the default RDC port 3389
I would like to make a remote desktop connection from the SBS2003 server to an outside terminal server that has been set up to listen on port 10941. How do I do this?

    Not a problem.
    Open the gui
    click on firewall policy
    righ-click firewall policy and select new access rule
    Give it a name
    select allow
    In selected protocols, click add
    select user-defined then click new - protocol at the top of the small window.
    call it rdp 10941
    Click new on the primary connection
    put 10941 in the start and end port box - click ok
    click next - next - finish
    Open the user-defined protocols and now select rdp 10941 then close - next
    In the rule sources, select add. Open networks and choose local host and internal
    click close - next
    in destinations, select external - close - next
    Select all users then finish. Apply the rule.

    Ensue tcp port 10941 is allowed out of your external router/firewall device.
    Job done :)

    Right on!.

    In doing this I noticed a built in rule "SBS Internet Access Rule" that appears to allow "All Outbound Traffic" fron "All Protected Networks" to "External" for "SBS Internet Users". Why isn't port 10941 already covered in this rule under "All Outbound Traffic"?

    because it covers traffic listed in the supplied, existing protocols. 10941 was not an existing protocol; you had to create it.
