Thanks for the details.

I don't think that you need to do port forwarding. Port forwarding
allows a program on a computer behind a router to act as a server,
i.e. to accept unsolicited connection requests from other hosts on the
Internet. When you run Windows Update or McAfee Update, your
computer acts as a client (requesting a connection), not as a server.
I've never had to configure a router to do port forwarding for Windows
Update or McAfee Update.

It's possible that your router has an MTU setting that needs to be
changed. Check Trend's web site for information.

Does your computer have a firewall program? If so, make sure that it
allows the program "Generic Host Process for Win32 Services" to access
the Internet. If it doesn't, Windows Update will fail as you
described.
