  • Multiple Remote Desktop Connections

    Hi all,

    I hope this is the right forum, if not, please move me


    Ok, here we go:

    The set up:

    Windows 2003 Enterprise Edition, legit copy
    - tomcat.realm.home
    - addr: 10.0.0.1, 10.0.0.10, 10.0.0.100
    - PDC (realm.home)
    - DNS
    - IIS
    - Remote Desktop enabled, listening on 3389

    Windows XP Pro, legit again
    - hawk.realm.home
    - addr: 10.0.0.2
    - client, Remote Desktop enabled, listening on 3390

    Windows XP Pro, you guessed it, legit
    - hornet.realm.home
    - addr: 10.0.0.3
    - client, Remote Desktop enabled, default port 3389, but RD not used yet

    Linux Mandrake 9.2
    - phantom.realm.home
    - addr: 10.0.0.4
    - not relevant to this problem...

    Alcatel Speedtouch Home tweaked to Pro
    - speedtouch.realm.home
    - addr: 10.0.0.138
    - ports open:
    Code:
    6          10.0.0.10:8099        0.0.0.0:443           0.0.0.0:0     template
    6          10.0.0.4:21           0.0.0.0:21            0.0.0.0:0     template
    6          10.0.0.4:22           0.0.0.0:22            0.0.0.0:0     template
    6          10.0.0.1:3389         0.0.0.0:3389          0.0.0.0:0     template
    6          10.0.0.4:80           0.0.0.0:80            0.0.0.0:0     template
    6          10.0.0.2:3390         0.0.0.0:3390          0.0.0.0:0     template

    The goal:

    I need to be able to make a simultanous remote desktop connection to both hawk & tomcat. Tomcat listens on 3389 and hawk listens on 3390. The ports (as you can see) are forwarded to the correct ip's, all inbound traffic on port 3389 goes to 10.0.0.1:3389, and all inbound traffic on port 3390 should go to 10.0.0.2:3390

    The problem:

    Only the connection to tomcat works. The connection to hawk on 3390 returns an error that the computer could not be contacted.

    Troubleshooting done this far:

    Portscan WAN addr: 3389 AND 3390 are open and accepting connections
    Portscan LAN (10.* addr's): 3389 on tomcat AND 3390 on hawk are open and accepting connections
    I tried specifying different ports for hawk, even 80, with no luck... (I stopped IIS and altered port fwd'ing when I did that)
    Connection FROM tomcat TO hawk on 3390 works fine
    Connection FROM hawk TO tomcat on 3389 works fine

    Ok, anyone idea's? I'm out of them... so please tell me, am I missing something here??? I'll feel very stupid, but hey, that's life. Please help...

    Does your router log indicate that the traffic is in fact being forwarded to the correct client? It sounds like your not making to the client.

      How can I check the router log on the Speedtouch Home [upgraded to Pro]?

      While trying to connect to hawk I can see an "instance" in NAT LIST on the router indicating my ip from where I try to connect, the correct inside port with the correct inside addr. Weird...

      Why do you think the traffic to tomcat on 3389 is beeing forwarded and traffic to hawk on 3390 is not? Is that possible?

      Thnx man!

        There's no logging option? Blah...

        It does sound like the router is the problem because you can connect locally but are unable to do so from the other side of the router. Unfortunately I don't know very much about your router so I can't say for certain the cause or the solution to the problem. Perhaps that question can be answered in the dedicated forum for Alcatel modems/routers.

              TCP, UDP checked?
