Okay, so I would like to use that SquidSoft video-con software, but I'm stuck. The software guide says that it supports NAT addressing (which I think I have) and that I need to set up my port. Can anyone walk me through this?

So..here's my setup: G4 desktop and iBook both with Airport cards...an (original) Airport Basestation...a router....my cable modem.

I went into the Airport Config and tried to 'add' a port under the Port Mapping tab, but it wouldn't let me do this because it said this doesn't work if I'm set up to share an IP address. Excuse me but, don't I have to share an IP address? I thought that was the whole idea behind NAT? So, if I shut this off, will it screw up my ability to get online with my desktop and my iBook at the same time?

Any help is appreciated.

Um... If I understand your setup correctly, the port mapping (or forwarding) needs to be setup at your router/firewall. You'll basically need to map the port(s) used for your Video-con software to your box. This way when others try to call you, they actually connect to your router which then forwards that traffic to your internal box.

Hope that helps.

And you'll probably want to assign a static IP to your computers. Do this in Sys Prefs> Network.

You need to set up static ip addresses before you do port mapping.

Okay...good advice. I'll set-up my (Airport?) for static IPs and look into setting up my (router?) for port mapping.

Note: I have never used Apple's Airport software, but am willing to bet it works similarly to other router soft.

Generally, the router (base station) allows you to specify a range of IP's for DHCP like:
xxx.xxx.xxx.100 through xxx.xxx.xxx.199
So to use a static IP, you don't turn off DHCP (at least you don't have to). Instead, you tell your computer (for OS X: in System Preferences > Network pane) to use an IP outside that range like:
xxx.xxx.xxx.2 (your BS is probably xxx.xxx.xxx.1)
You may also need to list the DNS servers. Just copy them from the Airport setup.

Thanks aaa, I forgo I could set some prefs right though the Network Prefs panel.
