I see logs shows Users are connecting internet via Zscaler using APIPA IP. Issue is very much intermediate and inconsistent. We notice users were connected from 3min to 30min to internet with APIPA IP address. We couldn’t reach the user during the active logs.
Most of them are offline or standby. So the machine might maintain keepalive session its application. However as per ZIA logs, machine can connect internet with APIPA IP address.
Issue happens only in GRE or Tun2.0 setup
i tried to replicate the scenario by bringing my home DHCP down. At this time, my internet is broken as expected since there is no GATEWAY IP assigned to my machine.
Do other see connection with APIPA IP in your office?
