Software Update doesn't work behind a firewall
All of the computers in my department are being moved behind a firewall. All of the computers running Mac OS X (either 10.3 or 10.4) cannot successfully run Software Update after being moved behind the firewall. Web pages load fine. SMB and AFP networking both work great. But when I try to check for new updates, I get the following message:
Networking errr has occurred: timed out (-1001). Make sure you can connect to the Internet, then try again.
Software update can't check for updates because of a network problem.
Strangely enough, it does appear that the computer is establishing a connection to an Apple server. I ran NETSTAT from a terminal window while Software Update was timing out, and it showed an ESTABLISHED connection to swscan.apple.com.
My understanding of our firewall's rule set is that all unsolicited incoming traffic is blocked, however all outgoing traffic is allowed. So, computer X can only talk to my computer if my computer contacts computer X first. Seems like this is a fairly standard firewall configuration.
I'm baffled as is the network guy I've been troubleshooting this problem with. Any ideas?
