Thanks guys but still not working. I am trying to reach a mail server that exists on our internal LAN (but in a different office on a different subnet) as an RFC 1918 address (as does my machine). I actually want to reach it via its public address ie out of our firewall acrross the internet and back in via the firewall in the other office.
Here is a the start of a traceroute, as you can see it goes out via the internet. dasterdly:/etc# traceroute azlan.com traceroute: Warning: azlan.com has multiple addresses; using 193.129.67.7 traceroute to azlan (193.129.67.7), 30 hops max, 38 byte packets 1 10.44.68.1 (10.44.68.1) 0.542 ms 0.441 ms 0.349 ms 2 * * * 3 gw4.lba1.gbb.uk.uu.net (158.43.227.4) 12.248 ms 10.513 ms 10.355 ms 4 fddi0-0.cr2.lba1.gbb.uk.uu.net (158.43.226.2) 10.792 ms 10.717 ms 10.650 ms 5 pos1-0.cr2.cbg1.gbb.uk.uu.net (158.43.254.126) 18.731 ms 18.802 ms 19.099 ms 6 pos0-1.cr2.lnd6.uk.gbb.uu.net (158.43.253.30) 21.447 ms 21.763 ms 21.818 ms 7 pos3-0.cr2.lnd8.gbb.uk.uu.net (158.43.253.145) 21.627 ms 21.540 ms 21.806 ms 8 ge2-0.cr1.lnd8.gbb.uk.uu.net (158.43.254.58) 21.669 ms 21.477 ms 21.891 ms 9 pos1-0.cr1.rea2.gbb.uk.uu.net (158.43.253.141) 20.242 ms 19.718 ms 19.818 ms 10 158.43.164.9 (158.43.164.9) 20.318 ms 20.591 ms 20.480 ms 11 azlagrou01-gw.pipex.net (193.129.67.126) 186.084 ms 93.238 ms 48.910 ms Here is where I telnet to port 25 (its a mail server). dasterdly:/etc# telnet azlan.com 25 Trying 10.44.65.120...
