As if we ever have hurricanes... Although sometimes after a night out
you'd need one to flush.... Oh no

I'm just extrapolating on the fact that the water circles in the wrong
direction when you flush the toilet in Aus.

I don't know, but I suppose that the Sun rises in the East, but then,
there are exceptions, like when you're in Australia and standing on your
head. However, I haven't tested this yet, but I suppose that it would
work, in spite of Microsoft's documentation otherwise.

Sort of like the old chestnuts:

And

And

I'm not - I'm saving that for the "engineer" and his tech lead.
It's just pisses me off when folks give "tribal knowledge"

Turning off ISA "solves many problems", too.
That doesn't validate the mitigation technique.

Jim,

I didn't want to get anyone in trouble.  After 3 hours I was sort of
beat, however in retrospect there is something else that should
corrected.
Unchecking the box did solve the problem.

This is incorrect.
I'll be speaking to the "engineer" tomorrow.
ISA 2004 supports "transparent proxy" for VPN clients with and without
the HTTP Filter.
Disabling that is a mistakw.

Jim,

Unless the Internal resource is across a VPN like in my case.  Ok, just
got off the phone with Microsoft.  Here is the problem:

1) I needed to uncheck Web Proxy Filter in the HTTP protocol rules.

Basically, I didn't have my browser set to use ISA 2004 as a proxy, I
was using it as a gateway for my client and I guess for some reason you
don't need the web proxy filter.

Which is really odd, since external worked, just not the VPN network.

Support thought it might be related to not having the external IP of the
destination gateway of the VPN in my IP for the VPN network on the ISA
2004
server however adding it didn't help.

Your definition is a waste.
There is no reason to force internal clients through ISA to internal
resources.

Dan,

The guy at Microsoft support said that there are two sessions with a
proxy connection like would happen with HTTP, however the connections
are made on the networks that are involved and not from Local Host.  So
in my case it is the Internal and Remote networks.  Which means that if
I am connecting from the Internal network with the ISA proxy the local
host doesn't need access to the Remote network.  My definition of proxy
in this case is two connection, client to ISA and ISA to web server, not
a bridge.

The ISA server itself is referred to as "Local Host" as far as policies
is concerned.  If you don't have a policy to allow you to connect from
the ISA server to your webserver, you will need to add one.  The
computers on your internal network probably are contacting the server
directly if they are on the same subnet.
