SSH tunneling uses what port?

Moebius · 10-03-2005, 01:37 PM

When I create an SSH tunnel, with port 25 for example, does it actually go through the firewall as port 25 or does it capture any local requests on port 25, transfer them through the tunnel on the standard SSH port, and deliver them on the remote machine to port 25?

Thanks!

If you setup an SSH tunnel, all traffic you asign to use the tunnel will use your SSH port. Im not entirley sure of the question...

I believe the answer to your question is "the 2nd thing" - all traffic through the firewall is sent through whatever port your SSH client connects to. Note, though, that when you create the tunnel you have to specify what port on the server you want your SSH client to redirect traffic to. I don't think that port 25 on the client automatically translates to port 25 on the server.

Hope this helps
