Hi,
a friend of mine has problems accessing a mail server from his company
but he can access my server.
I thought that I could enable port forwarding to solve his problem.
E.g.
D-S-MS
He wants to access the mail server (MS) from his Desktop (D). My Server
(S) is in the between.
I open a port on my firewall, let's say 12345 and let the user forward
the MS:25 port on that port. Note the MS server doesn't have ssh on.
Then instead of reading mail from MS:25 he reads it from S:12345.
Can I use port forwarding at the firewall level, or should I just use
SSH to do so?
You can use ssh. The downside to extensive use of ssh is that
you could wind up shoving most packets thru port 22. The whole
purpose of the firewall is pretty much defeated then, though.
Thus, if you wind up tunneling many ports thru 22, it might be
better to use a VPN.
