I'm using a Dell PowerConnect W-Series set of APs (W-AP205). My guest network is not allowing iphones to send or receive Gmail through the native IOS mail app.
The firmware is version 6.4.2.6-4.1.1.6_50009.
I have tried disabling all the intrusion protection settings. I am not blocking any kind of access or traffic on this guest network.
Native gmail app works fine on iPhones, as do Android mail clients.
This is affecting all iPhones in our organization.
Per another post on this forum, I also tried changing the network type from Guest to Employee. I did not see any UI for enabling specific ports.
Any advice on next steps?
