AutoDiscover not working behind WAF on 9.510

NickT

I have an Exchange 2010 server deployed behind an SG310 9.510.  I have Outlook Anywhere and Autodiscover configured.  Outlook Anywhere works, while autodiscover does not.  Creating a straight port forward for Autodiscover allows it to work.  Microsoft Remote Connectivity Analyzer returns the below.

Attempting to resolve the host name autodiscover.domain.com in DNS.
  The host name resolved successfully.
 
Additional Details
Testing TCP port 443 on host autodiscover.domain.com to ensure it's listening and open.
  The specified port is either blocked, not listening, or not producing the expected response.
   Tell me more about this issue and how to resolve it
 
  Additional Details
 
A network error occurred while communicating with the remote host.
Elapsed Time: 21041 ms.

I configured the virtual web server using the default Autodiscover policies in the firewall.

    Hi NickT,

    do you have any other services on the UTM e.g. User Portal or Remote Access that listen on port 443?

    If so change the port of the User Portal or Remote Access.

    Keep in mind that changing the remote access port need a configuration update on your clients.

    Best Regards

    I do have other services listening on port 443, but they are listening on different public IPs.  We have 2 WAN connections, each with a block of 5 static IPs.  I'll double check to make sure there are no conflicts.

    Interestingly, OWA works behind the WAF.
