Hello,
we have a Sophos UTM9 as a firewall in use. On our server in an Exchange 2010, the company is insalliert. I can login with an Iphone on the Exchange and everything works. When I'm mobile with my iphone the connection works with the Exchange over the established connection NAT properly. Now, I do not want to permanently enable the Exchange to the Internet through NAT, but set up the Exchange about WAF. This has also worked as far as possible, OWA works but the iphone can not connect to Exchange Server. A laptop with Outllook also gets no connection to Exchange, but NAT is equipped with everything.
Do you have any idea why the pure exchange service with WAF does not work?
