Router Port forwarding to multiple computers on a LAN

Hi all

Any solution to this problem.

I have for example a few machines up and running on a LAN (might be VM's but that shouldn't be an issue).

Say I have five with addresses 192.168.2.2 ==> 192.168.2.6

I might want to RDP to any of these from behind a router.

Using something like No-IP (No-IP - Dynamic DNS, Static DNS for Your Dynamic IP) I can get a an "Internet acessible" domain so I don't need to know the actual IP address that the Internet sees my router.

As I'm behind a router having Multiple domains won't help either as to the external Internet my router is seen as a single IP address.

However the router will only port forward to a single IP address on my LAN.

So if I need to RDP to any other machine on my LAN other than the default one presumably I could only do this by using a different default port for RDP for each of the machines on the LAN. OK not pretty but "Do-able".

Now we get to the real hassle -- If I did this then I'd need a different version of RDP on the CLIENT computer -- not possible if I'm using a work laptop .

Any solutions . I'm totally flumixed by this one.

Cheers
jimbo

Sounds like a job for Windows Home Server... which might solve some of your problems.

Many routers are able to set an inside port and an outside port for NAT configuration.

So you can assign different outside port routed to same inside port on different IP.
Example:

outside port - inside port - IP
9000 - 3389 - 192.168.0.1
9001 - 3389 - 192.168.0.2
etc.

When you need to connect to the 192.168.0.1 machine, you just have to use ISP IP:9001 and enjoy

But it depends on the modele of your router.

Other solution is to install live Mesh on the computer. Live Mesh remote desktop work fine and it's "IP independant", the connexion is made by "Device name"

Jimbo, i dont have the exact url to the thread on this forum, I think its in this subforum if not mistaken.... query your search for RDP and set to atleast 1 week old, i think its been probably 2 weeks now since we (bunch of us) were talking about this. And cant recall who to give the credit to exactly atm, but has a reg fix to specify or change the RDP port for each specific machine behind the NAT, since only one port at a time can be used. Good in depth thread, should be a sticky or tut IMO, if Brink hasnt made it already in the tut section. Could be around in there as well.

Thanks the IP:9001 type of solution worked fine.
great stuff.
