I'm unable to connect my IPAD to my citrix web interface using the receiver for IPAD. My Web interface external address is https://citrix.server.com:444
It seems that the receiver for IPAD only works with 443. Connecting to the internal web interface is no problem.
My client has only one public address and port 443 is already in use for OWA so that's why the Citrix WI is on port 444. I have done this trough port forwarding in my firewall.
So when I browse to the public address on port 444, all is forwarded to my CG on port 443.
