It has to be an Anonymous Rule:

From: <WSUS Server Computer Object>
To: <List of MS Servers or just use External>
Protocol: HTTP, HTTPS, FTP (not sure about FTP, but doesn't hurt to use it)
Users: All Users

Run the WSUS box as a FWC or a SecureNAT Client,...either should work

Then forget the ISA!

The ISA has nothing to do with this. It is a Web Caching Server only! The
WSUS is not "using the web browser" to get to the WU Servers.

Remove the FWC on the WSUS box,...the FWC is completely worthless with a
single-nic ISA.

The WSUS box will be using the PIX (and *only* the PIX) for this. So make
sure the PIX allows the traffic from the WSUS box.

Hi,

The WSUS Server is configured under the Proxy Tab with the name of the proxy
Server and port. The Proxy log does show the traffic being denied from my
WSUS Server when trying to retrieve Windows Update. What I found bizarre is
the traffic is getting denied with a Service request of "Web Proxy"
(Reverse). When I do a test from the IE browser on the WSUS Server with my
browser pointing to the ISA Server my request to www.windowsupdate.com works
fine??? NOTE: I do not have any FW client or Secure Nat configure on my WSUS
Server.

Any suggestions

Remove the proxy entries from WSUS. Make sure the gateway points to the
PIX.

Hi Asher,

I want the traffic to pass via the Proxy.

Yea. I know. Stop doing that.

I'm just trying to tell you if you want WSUS to work (which should be the
real goal here) then stop using the proxy and control the access directly
with the PIX,...in the end it is going out the PIX anyway, so just stop over
complicating it.

Leave the Proxy for the "humans" to use.

The use of a caching proxy is to minimize the internet traffic by caching
frequently used web pages locally. None of the WSUS traffic is repeated.
By using the proxy for WSUS you are doing 2 things. 1) over complicating
your network and 2) wasting valuable cache resources by caching the WSUS
downloads, which will never be used again.
