Server behind firewall

gdw · 02-27-2003, 12:18 AM

I have a computer set up as a server behind a firewall that I have absolutly no control of. A friend of mine has a computer outside of the firewall.

Is there some way I can access my computer via his computer if I open up some sort of connection from my computer to his?

For example, I can telnet to him, but he cannot telnet to me. Is there some other form of connection that I could initiate, that would allow a user to access my computer over the internet by bouncing through his computer which has a static IP?

no matter what the setup is, the server has to have the service started (listening for a connection)- whether its telnet, ssh, etc. So if you know one of these is running, you can try - but if its not, you can't do anything remotely until a service is somehow started on the server (I recommend ssh over telnet).

your message is a bit confusing...you want to contact the server behind the firewall remotely? If this is true...do you have control over the firewall? if you do, i'd simply forward the SSH port to your server. This would be very simple, not necessarily secure, but simple.

I have no control over the firewall. And yes, my goal in the end is to be able to remotly connect to a computer behind a firewall.

I was wondering if this could somehow be done using a server outside of the firewall as a go-between. The computer behind the firewall would initiate a session of something to the computer outside the firewall. That would get stuff through the firewall right? Obviously I know very little about what I'm talking about.

There is an internet site that offers this exact service, although I'm a day-glo pink rhino if I can remember what its called.

You open a session from your internal computer to this internet site, then you connect to the site from home, and bingo! you have a connection!. You also have a security hole that someone could fly a jumbo through but what the hell!

Do a bit of surfing, you should find it.
