I was trying to find a way to access my POP mail accounts from behind a firewall. I could do this from my PC by setting the IP address of the firewall as the default gateway (router), but there seemed no way to make the same settings on my Powerbook in OS X/Jaguar. The generous help from this List has enabled me - as a Unix newbie - to use the Unix commands in Terminal to set the router address to the firewall IP address, and now I am able to access my POP mail accounts through the firewall.... Quite impressive. I used: % sudo route delete default % sudo route add default <ip address of firewall> As with everything, easy when you know how. Thank you for sharing your knowledge. It has really been very helpful. regards, Trevor
