Hi all and thanks in advance.
long story short I have an ISA 2006 (existing), with a one leg configuration (one network adapter) on which I am trying to publish exchange 2010. The ISA acts as a proxy and I am having two issues:
- after creating the publishing rules the external clients cannot access exchange
- internal clients with proxy server enabled cannot access exchange (the owa https webpage for example)
so troubleshooting the issue I see that from the ISA computer I cannot browse to thathttps://mail.domain.com/owa address, which I should. and looking at the monitoring I see that it's being blocked by a system rule "system: allow http/https from isa server..."
I have firewall access rules that allow all outbound traffic from the localhost to the internal network so why would a system rule block it?
also I noticed that the internal network object covers all available IPs (from 0.0.0.1 to 255.255.255.254 with the exception of the loopback 127.x.x.x range).
any ideas on what might be causing this?
I've tried to exclude that mail.domain.com from the proxy on the ISA but no luck with that. And I do have the feeling that without having the ISA being able to browse tohttps://mail.domain.com/owa I will never get external access to work.
happy input would be much appreciated.
