Then the GFI will stop updating its definitions because of authentication failure, I opened a ticket with GFI support too.

If I add a web chaining rule that retrieve requests for the internal exchange directly, the publishing rule works fine. Is it ok to leave this web chaining rule in place or is it actually over writing the publishing rule and working on its own? Or else should I add an access rule between the ISA and the internal exchange? The exchange has a firewall client for the ISA, and it has the ISA as its default gateway, and the ISA can ping the OWA internal IP from the ISA correctly.
