iOS 11

NicholasHayman

Hi,

 

My college uses a captive portal web based authentication system on a Sophos UTM on their Wi-Fi. Since updating to iOS 11 when I connect it connects for a few seconds and gets a DHCP lease and then the connection just drops. Before I have a chance to login. They were able to reproduce the issue and said it's an iOS 11 issue then and I'd just have to wait for Apple to fix the bug. I don't think they're going to raise it with Apple or Sophos.

 

Has anyone had issues like this? I'd appreciate any input.

    iOS uses HTTP/2. Sophos does not support it - though it's been suggested already in 2015!

    Also the WAF is quite useless with the current iOS Mail App...

    HTTP/2 should be irrelevant for his problem, which seems to be with DHCP.  Only the school admin could say for sure.

    HTTP/2 is supposed to be optional.   When UTM is in the middle of the connection, it is supposed to clear the "HTTP/2 capable" header, so that the connection operates in regular HTTP where UTM can inspect it.  It would be interesting if someone can show that this predicted behavior does not match reality.
