FIELD

DESCRIPTION

Rule

This field is a sequential value, and it is not associated with a specific rule. The

sequence is important, however. The ZyXEL Device checks each active rule in

order, and it only follows the first one that applies.

Start Port

This field displays the beginning of the range of port numbers forwarded by this

rule.

End Port

This field displays the end of the range of port numbers forwarded by this rule.

If it is the same as the Start Port, only one port number is forwarded.

IP Address

This field displays the IP address of the server to which packet for the selected

port(s) are forwarded.
