We have had OWA set up and working for a while now, with our firewall mapping the external ip across to the exchange server.
I had to add an SSL cert as a few of our staff members are going to be using mobile devices.
The cert set up went fine, but now when I type https://our_external_ip_or_domain_name
it points us to the Firewall config page.
I tried setting up a rule to pass all SSL traffic to the exchange server but this didn't seem to help.
Our Firewall is a Fortigae 60.
