3. Unban the IP address using the command below. Use IP address and jail name from step 2:

   # plesk bin ip_ban --unban 203.0.113.2,plesk-panel

4. You can also unban multiple IP addresses by using a command that is similar to the following:

   # plesk bin ip_ban --unban [;203.0.113.2,plesk-panel; 203.0.113.3,plesk-apache]
