Cisco ASA 5505 Active Sync and OWA page

Posted on 2014-12-22
Last Modified: 2014-12-22

I am replacing an old Linksys with a less old Cisco ASA 5505.  I have the ASA partially working how I want.  The issue I am having is that I can't hit my OWA page from inside the network, and my ActiveSync won't work inside the network.  Both of these services are working from outside the network.  Please tell me how to get these services working from inside my network as well.  Below is my running config

The firewall shouldn't come into play here. Internally these devices should be going directly to Exchange.

I would check how you have DNS configured internally. Do you have split-brain DNS configured?

Also, need to know the version of Exchange you are on.

Hi Gareth,

Yup Thanks, that was it.  I could have swore I created the new zone.  However, I in fact didn't and once I did that made my records, flushed my dns cache it all started working.

So why does a Linksys router work without my split-dns, but an ASA doesn't?

Chances are the Cisco router blocks egress and the Linksys does not.

So, everything is good?
