Adding a Rule to a Static NAT Rule Set
To add a new rule to a rule set:
1.
From the Static NAT tab, select the rule set to which you want to add the rule.
2.
Click ( + ) at the upper left corner of the Static NAT tab.
3.
Select Add Rule to add a new rule to the selected rule set. The New Rule dialog box
appears.
Here, you must specify a unique name for the rule and set the conditions and the
action to be performed when the traffic matches these conditions, as follows:
a.
Enter a name, which uniquely identifies the rule within the rule set.
b.
Enter a destination address. The traffic from the source is routed to this destination.
c.
Enter an address prefix. Enter the IP address to which the source traffic must be
translated to. As static NAT supports one to one mapping, if your source consists
of a number of hosts, then make sure that you enter an equal number of public IP
addresses in this field.
