Add/Edit IP Address Mask Pair
The Add/Edit IP Address Mask Pair screen is used to enter both the IP
Address and Subnet Mask of both the local network (or machine) you
would like to protect and the remote network (or host) you would like to
protect it from.
A particular filter is applied only to traffic between the specific local and
remote networks (or hosts) shown in the list. If you wish to filter all
traffic, set the Remote IP Address and Subnet Mask both to '0.0.0.0'.
