Hi Mike,
 
Yep, that's a problem.

        lets take this one step further.
        on my upstream proxy, i see the logs rolling by, and i see
usernames and the IP address of the downstream proxy.
        ok, so that is what it is.. however, when viewing the monitoring
tab on the downstream proxy, I only see 'anonymous' on every session.
        How could one correlate those 'anonymouses' with the actual user
ID in the event that you need to trace back web activity to a
user\IPaddress combo?
        i only have authentication required on the upstream proxy,
otherwise, the users get prompted over and over to authenticate to get
out to the web.

        Hi Mike,
         
        Listen here little feller:
         
        If the Web Proxy Filter handles the request, then the source IP
address will always be the IP address of the ISA firewall.
         
        I'll stand by that until I have a chance to test it, or Jim
tells me I'm wrong :)

                on my upstream proxy, the before the firewall, its set
to Route, not NAT.
                if it was set to NAT, the upstream proxy's IP was shown.
                so, i was hoping my downstream would show the client IP

                        ya know i think its just odd.
                        right now my upstream proxy sends the client IP
to the firewall..

                        You can't have it both ways. If you want to use
the local Web proxy, you must accept the source IP address being that of
the downstream ISA firewall.

one place to watch the activity

                                What's the point of having them use the
local proxy? Why not just configure the clients to connect directly to
the upstream Web proxy and bypass proxy on the destination server? Turn
off Web proxy support on the downstream and away you go.

                                so basically i have to setup something
to tail what's being entered into the MSDE database as the users hit the
web, right?

                                Yes, but you won't have Web proxy
chaining. You need a ROUTE Network Rule and no Web proxy services at the
downstream. I.e., no local caching.

                                any way to have it log the IP address of
the actual client on the upstream ISA? it would make monitoring the
clients so much easier.

                                Another question.

                                When I watch my logs on the upstream
proxy, I see users coming thru with the IP address of the downstream
proxy, not of the client they are on.

                                Thoughts?
