Hello,
I have Microtik 4.9 with hotspot accounts
Please, help me to block all activity for range of IPs (eg.192.168.1.2-192.168.1.30) on firewall roules

/ip firewall address-list
:for LASTOCTET from=2 to=30 step=1 do={
add list=blockedClients address="192.168.1.$LASTOCTET";
}
/ip firewall filter
add chain=input action=drop src-address-list=blockedClients
add chain=output action=drop dst-address-list=blockedClients
add chain=forward action=drop src-address-list=blockedClients
add chain=forward action=drop dst-address-list=blockedClients

Make sure the filter rules are above anything that might permit that traffic.

Drag and drop it in Winbox, or use the CLI:

/ip firewall filter move [oldid] [newid]
