pfBlockerNG - FireWall rules
-
Hello,
As of today I have installed pfBlockerNG on our firewall. We do this because we see many incoming attacks. Now I have put the TOP spammers on Deny Inbound. This also for the other continents. The only thing that may actually come inbound is the Netherlands.
Only a Dutch IP will be placed under United Kingdom GB_rep. Every time I whiteList this IP nothing happens with it. If I do not select the GB_rep and do the update it will work again from the IP address of our client.
Do you have any tips? Could I perhaps configure it better in a different way?
This is an example:
It's about different ports. But these are unfortunately necessary for webmail and autodiscover.
