How does Smart DNS work?
My SEP version is 12.1.
I have already enabled "Smart DNS" in built-in rules of firewall policy.
but sometimes i can still see in the logs the port of tcp/udp 53 was blocked by the firewall.
( i disabled the rule "allow all applications")
can someone tell me how does Smart DNS work? and need i create a rule to allow tcp/udp 53 even if i enable "Smart DNS"? if i needn't, so shall i ignore the logs?
thanks a lot.
