    I have a Mac Pro wired to my home router via ethernet, port 1. I want to use "Internet Sharing" to let an XP / Ubuntu box connected to ethernet port 2 get out to the web, like the rest of the machines on my home LAN.

    I can't seem to get this to work.

    The Mac Pro is not using DHCP to connect to the router, it's a set IP I've indicated (it's at I am fine if the XP / Ubuntu box is using DHCP or manual settings.

    I am able to go directly to from the XP / Ubuntu box, but nowhere outside. I have tried manually entering the DNS settings of the Mac Pro into the XP box, to no avail.

    Can someone tell me exactly how this needs to be setup? Thanks.

    I've never had a Mac with two Ethernet ports but if Mac OS X is just like BSD UNIX (It should be) I used that quite a bit. The technical words are "The MP is but 'routing'" There has to by some way to enable routing between the two Ethernet ports

    BTW are the to ports on the same network? )You only told us one IP address, what address is the second ethernet interface?) I would think they shouldn't be. I'd have the second one on a network and enable routing, or maybe routing just starts working ones theports are on different networks.

    Why can't you simply plug the PC box into your router. Out of ports? Buy a hub or switch, they are cheap.
