– This example adds three rules:
1. Accept any incoming packets if the source address is in 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.
2. Allow TCP packets from class C addresses 192.168.1.0 to any
destination address when set for destination TCP port 80 (i.e., HTTP).
