Re: iChat and the PIX

[Joe Marshall <JMarshall () FREDERICK EDU>]

We followed Apple's document on getting iChat to work through a firewall
with NAT.  Granted, we do not have a PIX, but the ports are all
explained in the link below.  There are a lot more than just port
5060...

If your campus is using a Cisco PIX, can you please read this and see
if
you have any advice? Our problem has been escalated by a parent to our

President's office...

We have a problem with a student not being able to use iChat from our
campus network. We have run numerous tests from public and private IP's

through our Cisco PIX and we have run numerous tests from other
networks
that don't go through the PIX and it seems we have narrowed down a
problem that our NAT and PAT users cannot use iChat through our PIX if

talking to another user off campus that also has a private IP address.


We have tried "fixup protocol sip 5060" on and off and still no
success.

Does anybody have any experience getting iChat to work correctly
through
a PIX?

Thanks in advance,
