Hi everyone,
We are using PAN OS 9.1.5.
Our internal hosts and DNS server are in different PA Zones.
We have a policy to allow all hosts to access DNS servers with application "dns".
We used strict anti spyware profile on the above mentioned security policy.
After applying anti-spyware profile, we see that the DNS queries timeout most of the times and very rarely when they work, the queries will take a long time.
As soon as we remove the Anti Spyware profile, everything woks normally. I am totally lost and cant find the root cause. Since there are no logs as well!!
Is this any known issue? Does anyone else have similar problem?
Thanks!
