Hi,

I'm a bit confused. Using ARD 3, When I try to set up more then one computer via wan that is behind an airport extreme a/b/g it only allows port forwarding to one internal ip.

It also doesn't allow me to change the ports via the aiport option in the firewall. I don't even know if you can use other ports for ARD...

Any suggesions? People must have more then one client at a single ip behind an airport...

I know I could use vnc for one and ard for the other, but I would be losing functionality of ard...

Is this possible to do? Or is this a limitation of ARD?/Airport?

    Hi Shaun!

    Port forwarding in home routers is pretty limited. But you do have some options when dealing with mulitple machines.

    1. (I have not tested this.) You may be able to set up a second port forward port for your second machine.

    On your router you're already port forwarding 3283 to your first Mac at 3283. Try port forwarding 3284 to your second Mac at 3283. Then in ARD enter the IP address of the second machine as 192.168.0.1:3284.

    2. You could invest in a home router that supports VPN. When connected via VPN your own computer would effectively be on the same network as your remote Macs and should be able to see everything.

    Hope this helps!

    Shaun,
    I've used Hamachi for PCs and it's great!!

    I'd love to put in on our Macs at work but it requires a command-line install.
    (I know next to nothing about unix C-L)
    I downloaded the program and hamachix for the GUI, but HOW DO I INSTALL IT???

    Any help of suggestions GREATLY appreciated!

    Since this issue is not related to Apple Remote Desktop, the discussion should probably be moved to another forum. There's one specifically for Hamatchi questions here.

    Good luck.

    Thanks Dave.
    I've been through that forum, but it hasn't been very helpful for users not familiar with unix commands.

    If you need help with UNIX commands under Mac OS X, the Mac OS X - UNIX forum should be a good place to ask.

    OK, getting back to the original topic and away from the Hamatchi issue:

    The nature of TCP/IP allows a port to only be forwarded to a single IP address. That's not a function of the router, that's inherent in the design of the protocol. If your workstations get their addresses from an NAT device rather than being "real", the ports need to be forwarded in the router to the workstation's internal IP address. ARD uses port 3283 for the reporting and updating function, so if your Macs are getting their IP addresses through NAT, since you can only forward a port to a single workstation, you can only get reports, push package/files to etc. for a single workstation.

    ARD uses the VNC protocol for observation and control, though, and there are a range of IP addresses for that protocol, starting with 5900. ARD uses 5900 by default, so that port would be forwarded to the first workstation. You would, I believe, need to install VNC servers on the systems (since the ARD client cannot listen on any port other than 5900 while VNC servers can be set for other ports such as 5901, 5902, etc. You would then forward 5901 to the second workstation (and on to 5902, 5903, etc.). You can then use the following information:

    Remote Desktop 2: How to specify a port number for a VNC client

    to connect.

    The only other options are: 1) to run the ARD administrator on a workstation on the network, and then take control of that system from outside, either via VNC or another copy of ARD, or 2) set up a virtual private network (VPN) so that when you connect from outside, your admin system is officially part of the local network.

    Hope this helps.
