IOS device finds MX700, but wont connect over wi-fi network to initiate session

[ekds]

We are testing in our VC lab, iPhone (on corp wifi) will find MX700 device, but times out with "can't connect to network" and won't begin session. 

I am guessing ports in FireWall need to be opened between out corp wireless and wired LAN networks.... anybody know what numbers we need to set and or settings on network side we need to look at?

Only HTTPS, port 443, is required. The HTTPS service also needs to be enabled on the MX700, which it should be by default,
