    Hi, We are running GRE tunnels between controllers in DMZ and those on local sites for Guest/BYOD traffic. After an outage where tunnels went down all seems to be fixed today, but we are seeing some strange behaviour. Users are not able to obtain the IP address in expected range, and in user-table on local controller we are seeing Guest/BYOD VLAN interfaces from DMZ controller (see attachment). Any thoughts? Thanks.

    That means that on the local controller side, your GRE tunnel is untrusted.  Make it trusted.
