Hello, We have been running OWA & OMA successfully for over a 8 months. We publish Exchange 2003 through ISA 2004 (SP1) both on Windows 2003. We are looking to implement Message Labs web content filtering and have setup a trial. To implement this it involves installing a proxy agent on to ISA and setting up a upstream proxy in the last default rule of the web chaining to the Message labs servers. This works fine however when we switch over to the service OMA And OWA stops working. I have read articles on direct access and spilt DNS but am not getting very far I was wondering if someone could point me in the right direction.  Thanks

Hi Stooie,

Is the Message Labs solution for forward or reverse proxy?

Thanks!
Tom

Hello Tom,

Thanks for the reply.

I belive it is a foward proxy. All of are HTTP & HTTPS goes up to them and the filtering is done at their end for content, anti-virus and spyware.

Hi Stooie,

OK, in that case none of the OMA/ActiveSync traffic should be going to the Message Labs box, right?

Thanks!
Tom

the most likely cause will be DNS.

can you check to make sure that the DNS address of you OWA and OMA are set to point straight at your ISA and not Message Labs.

We use message labs here and still have OWA in place.

Is this on the web chaining rule? If so the to tab has all networks. The publishing rules in the fiwewall policy are from the listner to the exchange server on its local ip address.

Thanks
