This aught to give you an idea.
Except for 192.168.x.x (Private network) numbers
these ip addresses are for this discussion.
You change the 24.x.x.xx to your ISP numbers.
Use the 192.168.x.x so your internal lan/private network routes correctly.
24.x.x.xx is your ISP assigned address.
ggg.ggg.ggg.1 is your ISP gateway/router.
fw is my firewall.
I borrowed hysterion's (on MindSpring Enterprises) drawing
