  • Create a new Protocol definition for RDP in Cisco ASA5510

    I'm configuring a Cisco ASA5510 to allow RDP into the private network, from the internet (port 3389) so that home users can use WinXP RDP to log into the Win2003 Terminal Server.

    I don't think the ASA has a definition for RDP protocol so I wanted to make one. I want to create a protocol defined as port 3389, call it "RDP" and then configure a policy to allow incoming RDP traffic to the Terminal Server.

    Can this be done in the Cisco ASDM software?

    I think I found the answer....Service Groups. Edit a Security Policy and you will find a button called "Manage Service Groups". I defined a SG called "RDP" with port 3389 to 3389.

      Hi JDMils
      Can you help to give any way to do it by CLI if you have it, I think you did it through GUI ??
      Thanks you for sharing your knowledges

        Aitymo, Just add a static for that port to your Term Serv.

        static (inside,outside) tcp [ExternalIP] 3389 [InternalIP] 3389 netmask [MASK]
        You can not name the protocol when using the CLI and thus have to use the physical port number.

        Yes, I use the ASDM interface which runs off the ASA's internal web server.

          Hi JDMills,
          Thanks for your question and answer on the ASA. I'd like to hear more about your ASA configs and your impression of the box as you use it more.

            In CLI do:

            conf t
            object-group service <servicename> <tcp/udp>
            port-object eq <portnumber>
            exit

            for example

            object-group service oracle-1542 tcp
            port-object eq 1542
            exit

            HTH
