For single port situations, redir and ipportfw have the same result,
although the methods of achieving it.
ipportfw works via firewall rules. It runs, modifies/adds/deletes
rules as you wish, then terminates. Hence, it is able to forward a
range of addresses.
telprox, and redir however, are programs that run, sitting on a
port. When it gets a connection, it opens the destination port on the
destination machine. It ony handles one port at a time, and the
machine (firewall) doing the forwarding is logged as the "source
machine". I.E. if I telnet to mercury.merconline.com, port 1000, and
it uses telprox/redir to forward to jupiter.merconline.com, port 23,
I will see via the "last" command:
irc ttyp3 mercury Sun Mar 1 12:56 - 12:56 (00:00)
irc ttyp0 mercury Fri Feb 27 22:30 - 22:40 (00:10)
Note: He's not really telneting from mercury, in the conventional
sense. He's coming telnetting in from somewhere else, then getting
forwarded from mercury. Let's take a look at "last" after I moved to
ipportfw:
irc ttyp1 d190.dial-1.cmb. Sat Mar 7 00:03 - 00:03 (00:00)
irc ttyp1 d190.dial-1.cmb. Sat Mar 7 00:01 - 00:03 (00:01)
irc ttyp0 1Cust108.max6.ka Wed Mar 4 00:17 - 00:28 (00:11)
irc ttyp3 wm-dyn40.whitemt Mon Mar 2 16:08 - 16:10 (00:01)
