We have a Sonicwall TZ600 and have noticed that someone on the WAN is using port 53 UDP to access our LAN.
I have verified the we have rules built to DENY anything for IPV4 and 6 from WAN to LAN and WAN to WAN but doesn't seem to deter the problem.
I have also made sure that the Comprehensive Gateway and Security services are enabled.
Any ideas?
