3. Block an entire subnet 1.2.3.4/16 or a separate IP address

Press the button "Add new filter" -> choose "IP network" -> simply type any IP address (field 1) and press the button "Blacklist" to add it to your Blacklist.

Subnet blocking:

1.2.3.4 - IP address,

/16 - subnet mask

If you don't know how it works simply put numbers for mask divisible by 8:

  • 1.2.3.4/8 - all IP addresses starting from 1.n.n.n (from 1.0.0.0 to 1.255.255.255) will be blocked.
  • 1.2.3.4/16 - all IP addresses starting from 1.2.n.n (from 1.2.0.0 to 1.2.255.255) will be blocked.
  • 1.2.3.4/24 - all IP addresses starting from 1.2.3.n (from 1.2.3.0 to 1.2.3.255) will be blocked.

Add SpamFirewall record

4. Make sure that newly appeared entry has in the column "Service" value "SpamFireWall" or "AntiSpam"

It is essential to changes take effect even if you haven't change the settings. If you don't do this, changes will take effect only in 24 hours.
