> I have a default internal network, I have a default external
> network, I have an added perimiter network
> I have only one nic enabled right now, I'm still testing web
> proxy features
> I want to enable web proxies for internal and perimiter
> networks which I think I did correctly, at least everything
> is working when traffic originates from my internal network
>
> However: my scenario includes various remote webservers only
> reachable via vpn tunnles. The remote web servers will only
> accept traffic originating in our internal network. Whilst
> playing around with this scenario I noticed the following:
> I have set up an access rule allowing everything from
> perimiter to ISA server, later on this will again be reduced
> to whatever is actually needed. On a host in the perimiter I
> entered the internal IP of ISA as the proxy, the perimiter
> actually gets 'routed' across a PIX sitting in between as
> well. I then try to access a remote web server, however,
> access is denied. ISA's monitor denies access to port 8080.
> The originating IP is taht of the actual host, target is ISA.
> The access rule permits everything from perimiter to ISA.
>
> I created the perimiter network as a network enabling the
> proxy on it as well as a network range containing the IPs of
> the perimiter network. I tried combinations of various
> objects in the access rule, finally opening up everything,
