I have three Macs running OS X 10.2.3. They are behind a Windows ISA firewall, and can't retrieve software updates. I want to know the TCP/IP port that Software Update uses, so I can allow it on the firewall. If you know the port, please respond.

While I don't know the port off of the top of my head, doesn't the firewall have logs that tell you what it's dropping?

A quick search on Apple's support site shows that "software update" can't function through a firewall/proxy that requires authentication... They recommend going to the updates web site and working from there.

Yes, but there is so much traffic being blocked by the firewall that I can't determine which port is the software update request.
I've seen the posting on Apple's website. Normally I would have just added the proper authentication, but after reading Apple's post, I know I can't do that, which is why I'm trying to find the specific port. They don't seem to document it, though.
Thanks for the pointers, but I need the specific ports to give out points.

It's not port 80. I have port 80 open to allow http traffic, so if it were port 80, the problem wouldn't occur.

Well, everything points to it being port 80, though I hate to tell you so. Also, you won't look at your firewall settings for how they are working [and check the logs] so you're not going to get anywhere that way.

Here's a likely solution that others have found quite helpful for software updates as well as iTunes and other such things...

Actually, I have looked at my firewall settings and checked the logs. The problem is that after opening numerous ports based on the logs with no success, I decided to stop randomly entering rules and just ask a question. Thansk for the link, anyway.Still hoping for a straightforward answer from Apple or anybody else.

Dpetrak, Authoxy works. Post one more question and I'll award you the points. You deserve them for figuring out that it was an authentication problem rather than a blocked port. And yes, it was port 80.
