I've got a dual M3/AOS 6.0 system and my internet firewalls are casting off a number of outbound pings to OpenDNS from the controller IP. Only my guest profile uses OpenDNS. The Controller address is the PAT address for the guest users. The guest policy does not permit ICMP, so it appears to be the controller itself. Am I correct, and how would I fix? I will be pointing guest users to a new DNS server in our DMZ in the future obviating the problem, but wanted to understand the behavior anyway.
