I have v9 running in front of an Exchange 2013 server. The real server is internal.example.com and the virtual server is mail.example.com. When I point my browser at https://mail.example.com/ecp/ I get a response but then the url changes to https://internal.example.com/ecp/blahblah and everything stops since that address is not in DNS outside the LAN.
If I point to https://internal.example.com/ecp/ from the internal LAN everything works. Which should be obvious since I am not hitting the firewall.
If I turn off WAF and use NAT port forwarding, address https://mail.example.com/ecp/ works just fine and stays as mail.example.com.
All the virtual directories in Exchange are configured for the external address.
Thoughts on what is going on or ideas how to troubleshoot?
