Hi I have use my Mikrotik sometime and I like it alot.
But I have not work with it so much but I have a question about wildcard and block in firewall

If I use this command i terminal in Mikrotik

/ip firewall filter add chain=input src-address=83.240.61.62 action=drop

It then block the 83.240.61.32 to access to my router.

But what can I do if I like to block

83.240.61.*

or even

83.240.*.*

or something like that?

Use CIDR notation, e.g. src-address=83.240.61.0/24 or src-address=83.240.0.0/16.

You can also enter a range between two ip addresses. If those can be written short by CIDR then the they will converted by ROS.

Example: 83.240.61.5-83.240.61.201
