Apple IChat problem?

JJ

Has anyone else heard of / had problems using Apple's iChatAV with Verizon FiOS?

I just switched from Verizon DSL to FiOS and now iChat will not connect. I can see when folks are on and their status, but I cannot connect to them.

Could it be a port blocking issue? Is there a tutorial somewhere on how to set up the FiOS router to allow a specific port range?

Skype works just fine, so it is definitely an iChat issue.

Thanks!

OK, an update, since I got things working after a little research. Found the Portforward.com page for my router (Actiontec MI-424-WRv2) and the support.apple.com pages:

and

(for OSX 10.5 only)

(for other OSX's)

For OSX 10.5, you need open only UDP ports 16384-16403 and (perhaps) UDP port 5678. I set both of these according to the portforwarding.com instructions. I did not open any other ports or turn off UPnP. For other OSX's you may need to open other ports (see the portforwarding.com page for your router model).

Tried iChat today and everything works. It is too bad that I had to be somewhat knowledgeable to get this done. Most of the users out there wouldn't have a clue where to begin with this stuff.
