Remote control through firewall

January 12, 2005 at 20:05:49
Specs: Win XP, Pentium 512 RAM

This is the situation: There are two computers behind firewalls (routers,) one can be port forwarded in the router's config panel, and the other one cannot (I dont have access to the router's settings)

Whats needed is to be able to access the one behind the router that cannot be changed. I thought to use VNC but didnt see how that would work out if the ports are simply not going to be forwarded to that machine...

It seems from the searches that I have done that the way to do it is through 'SSH' and I have downloaded and tried a bit with it but did not get it going. Of course if I tried more and decided that this is the only way then it would probably work.

My question is this: is the only way to access a remote computer that is behind a Firewall through SSH? And if yes, what is the simplest and most straightforward way to do it? ANd of course if SSH is not the only way, what other ideas are there?

Well, I have 4 PCs at home. My solution was to forward port 3389 to my File Server which is on 24/7. Once I connect to that PC with Remote Desktop, I simply Remote Desktop from that computer to my other computers! Works great.

Of course if the one computer that is being forward to is not on all the time, that could be a problem. :)

PCanywhere also does a good job at passing through the routers!

Thanks, but I dont have access to one of the routers (the 'server' side- the one that needs to be accessed) in order to port forward. Basically, even if I have the IP address I could not get to that computer because, for example, VNC just gets stuck by the router which doesnt know where to send port 5900... Of course the best thing might be if I could set up forwarding, but I dont have access to the router config.

Any ideas for such a situation?

I have the same situation, did you find a way to resolve it ? I have 1 Machine behind a router towhich I dont have access, and other one to which I have control.
In case you find a solution , please email me or post it here,

The only 2 solutions I found are with GoToMyPC (19$/month) that seem to pass trough corporate firewall withouth problem. And the built-in remote assistance in Windows XP but someone needs to send the invitaion from the server side with msn messenger... Not good if you are outside...

From what I see one can possibly use a 'http tunnel' software or VPN connection (or SSH) to get through. When I asked the question I actually found a way to do it but didnt implement it because it wasnt urgent and it seemed very complicated.

In short- there is definitely a way, the question is how difficult it is...

Good luck to everyone (myself included)
Thanks for your help guys,
