Web – Specify the action (i.e., Permit or Deny). Specify the source and/or
destination addresses. Select the address type (Any, Host, or IP). If you select

mask for an address range. Set any other required criteria, such as service type,
protocol type, or TCP control code. Then click Add.

CLI – This example adds two 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).
(3) Permit all TCP packets from class C addresses 192.168.1.0 with the TCP control
code set to “SYN.”
