#

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 rule in order,

 

and it only follows the first one that applies.

 

 

Active

Select this to enable this rule. Clear this to disable this rule.

 

 

Name

This field displays the name of the rule. It does not have to be unique.

 

 

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.

 

 

Server IP Address

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

 

port(s) are forwarded.
