Use an IP address mask

To enter an IP address mask with the Firewall tool:

• Use the entire IP address, such as: 192.168.149.55

• Use a portion of an IP address and asterisks; an asterisk in an IP address field matches any number.

  If you use a portion of an IP address, such as 192.168.177.*, the PI Firewall denies or allows access for all computers with IP addresses that begin with 192.168.177.

  Note: If the address mask is already used for a PI Firewall, the existing entry of the same name is overwritten.
