I have just been going through ** to get iChat working with a BT Voyager 205 modem/router.
In the end I contacted Apple and an extremely helpful iChat Engineer from Apple contacted me. With his patient advice and tutor-ship we succeeded in making it all work perfectly.
And what you have to do is a 2 minute job. This is a direct cut n paste of his email to me less my IP address, you just put in yours. No port forwarding or port triggering nonsense. No static IP rubbish. It's all in the Voyager.
Here you go:
Open up a web browser and access the 205 control panel at http://192.168.1.1
Select the 'Advanced' option on the left of the screen to open up the advanced configuration page and then click the 'Advanced....' option.
Enter your username and password when prompted, the default username is 'admin' and the default password is also 'admin'.
Select the 'IP Routing' option in the menu on the left and then choose 'NAT Virtual Server/DMZ' from the NAT Options.
Left click on the 'Add' button and then select 'DMZ' from the rule flavour menu.
Enter a number not previously used by another rule into the 'Rule ID' box, '60' should be fine for most people.
In the 'LAN IP Address' enter the IP address of the Mac found in Network Prefs(I guess it is 192.168.1.XX)
Left click on the 'Apply' button and then left click on the red 'Save' button on the left.
You should then get a confirmation window which you can just close.
All done.
You have now put your Mac in front of the Voyagers Firewall in something called the DMZ or DeMilitarized Zone. If you don't want anymore tinkering, turn your Firewall off in Sharing Prefs and you are good to go.
If you feel insecure you then need to open a few ports in your Mac's Firewall in Sharing prefs.
Click Add and a sheet opens.
In the Port Name select Other
TCP Ports add 5190, 5298 (type them in exactly as I write them here)
UDP Port Numbers add 5060, 5190, 5297, 5298, 5353, 5678, 16384-16403 (type them in exactly as I write them here)
Description add iChat AV to give it a name.
Click OK
Then turn your Mac Firewall on. What you have just done means that though your Mac is not protected by the Voyagers Firewall, it is protecting itself. However, opening those ports allows iChat to communicate through the Mac's Firewall.
Now enjoy iChat.
This tutorial assumes you are using Tiger and Panther.
