Avocent PS/2 IP User Manual page 50

IP/Mask
Specifies the IP address or IP address range for which the rule applies.
Examples (the number concatenated to an IP address with a " / " is the number of valid
bits that will be used of the given IP address):
192.168.1.22/32 matches the IP Address 192.168.1.22
192.168.1.0/24 matches all IP packets with source addresses from 192.168.1.0 to
192.168.1.255
0.0.0.0/0 matches any IP packet
Policy
The policy determines what to do with matching packets. They can be either accepted or
dropped.
The order of the rules is important. The rules are checked in ascending order until
a rule matches. All the rules below the matching one will be ignored. The default
policy applies if no match has been found.

Inserting a rule

"Replace".
