Example
This example accepts any incoming packets if the source address is within
subnet 10.7.1.x. For example, if the rule is matched; i.e., the rule (10.7.1.0
& 255.255.255.0) equals the masked address (10.7.1.2 & 255.255.255.0),
the packet passes through.
This allows TCP packets from class C addresses 192.168.1.0 to any
destination address when set for destination TCP port 80 (i.e., HTTP).
This permits all TCP packets from class C addresses 192.168.1.0 with the
TCP control code set to “SYN.”
