Port forwarding for the rest of us?

Question

Hi all,
I've been reading this forum for a couple of weeks now trying to find a way to get two Macs to do iChat video.
1st setup is a G5 MP2.0, 10.4.7, iChat 3.1.5, iSight, Belkin 8230-4 router.
2nd setup is iMac intel 20", 10.4.7, iChat 3.1.X, builtin camera, Airport Extreme router.
Both are on 1.5+ broadband, Belkin has a static IP coming into the router, with the G5 connected using DHCP with manual address. Airport has cable modem DHCP in, with DHCP/NAT turned on. Apple firewall is OFF on both.
Initial tries yielded the dreaded -8 error. I reset Quicktime streaming, iChat bandwidth prefs as suggested and tried forwarding ports on both setups, per the portforward.com recs for iChat.
The Intel iMac is now able to see/hear the ads on the auto chat test from appleu3test01 just fine, but we're still getting -8 when trying to connect to the G5/Belkin.
Besides the six initial ports for iChat (portforward.com) have now tried a shotgun approach by adding ports suggested from various sites/forums. This setup has achieved at least an error free connection with the auto testers, however the intermittent blocky video and choppy sound is not much better. Screen grab of blocky video with the 20 forwards currently set on the Belkin.

I'm looking for help sorting this mess out. What am I doing wrong here?
Thanks in advance for any help.

P.S. I was going to post my first ever anti-apple rant... if only just to feel better but, what's that? oh okay...
<rant> Dear Steve, Even tho I have been using Macs since the 512, I am one of those artsy fartsy Mac users who doesn't really want to know what is under the hood. Admittedly, I am newbie at all this router port stuff, but the fact that lots of people seem to be having this same problem is ridiculous IMHO. Even the Yahoo and Skype Beta video ran the first time we tried it, not great quality, but it was a no brainer setup and it just works... exactly what we've come to expect from Apple. If these johnny come latelys can do it this simply, why can't my fruitbox company of choice get their own ***** sorted out? </rant> Sorry Steve.

Hi PMck,
This device can do Port Triggering even if it can not do UPnP.
At present the Port Forward site list their own PC app to help.
The method though is here
Ignor the pics and info on the brown and orange pics.
Set the first trigger as port 5678 on UDP.
Set these ports in the next text field
5060,5678,16384-16403 (no spaces and only commas and dashes inbetween) Set the protocol for these as UDP as well
Set a new line for trigger 5190 on TCP
Set the next text field as just 5190 and TCP again
Repeat the line above but for UDP at both points
If using Jabber at all:
Set a trigger of 5222 on TCP and ports 5220,5222 on TCP
(if using GoogleTalk make that 5223 on TCP and list 5220,5222,5223 on TCP)
Bonjour needs four single lines (trigger and just one port in the list field)
5297 on UDP 5297 on UDP
5298 on UDP 5298 on UDP
Repeat for TCP for 5298
5353 on UDP 5353 on UDP
As this is a NAT method of opening the ports the Airport will need "Distributing Addressing" turned Off in the Aipor Admin Utlity > Network tab This will make the Airport just an access point and the Belkin will address the whole Lan then.
Thios will allow multiple copmuters to access the same ports for iChat at the same time. The Belkin can be left doing DHCP. (Or be set to Static to the LAN)
Turning Off DHCP in the Airport (Distributing Addresses) will avoid any Double NAT and Double DHCP that seems to be going on at the moment.
