Hi guys.
To make nice filter against mailware sites I added 2000 dns addresses in Firewall >> Address List
The problem is that Mikrotik each few seconds make DNS resolve of those 2000 sites. So he open 2000 sessions each few seconds that harm network a lot.
I see 2 options to solve that problem:
1)stop using dns addresses in Address list
2)change timer for DNS resolve from few seconds to 1 day
How I can achieve second option?
