Ok, just to make sure I'm understanding you here. We're dealing with 3
machines. The XP one that your parents have isn't all that important.
For the other two, I'm kind of confused what you meant. This is what I'm
understanding:

1) A Debian server somewhere with port 4567 being forwarded to port 22
on your home PC. (This server is NOT at your home)
2) A Debian PC at home with only port 80 publicly available, and with
port 22 (presumably) open only to connections from the IP of box #1.

If this is correct, then you can just connect to box #1 and do a direct
SSH connection to #2. If the port-forwarding isn't working it's either
because #1 isn't doing the forwarding correctly, or because #2 is down.

If I'm not understanding you correctly here, then please give us some
more details on how exactly the two boxes are connected.

I don't believe there's any way to do this. SSH server and client
processes only work in the direction they're supposed to, to the best of
my knowledge.

But if I got the part in #1 right, then you shouldn't need to get to
this point anyway.
