Destination IP Address – specified the same as Source IP

Destination Netmask – specified the same as Source Netmask

Destination port(s)

– specified the same as Source port

Network protocol – network protocol which the rule affects. Can be specified as

one of TCP/UDP/ICMP or any

i Hint: If an exact port is specified, use of “any” protocol setting makes no sense

(different protocols use their own port ranges). Use exact protocol, or use several rules

to specify traffic filtering on required ports.

~Note: When defining rules, avoid DENY type rules using “any” as the address class,

which can cause loss of web management connection (e.g., deny traffic from any to any

IP address). In such case, only connection via serial console, manually disabling the

firewall or hardware reset the device to factory default to disable the firewall setting, can

rectify this problem.
