Allow Permanently

The permanently allow area allows you to manage IP addresses that are permanently allowed through the firewall.

IP addresses listed here will NOT be ignored by the login failure daemon. If you do not want the login failure daemon to block an IP address you must add it to the Ignore section.

IP address 203.0.113.1
CIDR 203.0.113.0/24
Filter tcp/udp/icmp|in/out|s/d=port|s/d=ip|u=uid
