Wildcard Mask. Defines the source IP address wildcard mask. Wildcard masks specify which bits are used and
which bits are ignored. A wild card mask of 255.255.255.255 indicates that no bit is important. A wildcard of
0.0.0.0 indicates that all the bits are important. For example, if the source IP address 149.36.184.198 and the
wildcard mask is 255.36.184.00, the first eight bits of the IP address are ignored, while the last eight bits are
used.
