1. Display the NAT Rule – Add Page, choose a Rule ID, and
select RDR as the Rule Flavor.
2. Select the interface and, if desired, a protocol that this rule
applies to.
3. In the Local Address From / To fields, type the same
private IP address, or the lowest and highest addresses in
a range:
•
If you type the same IP address in both fields,
incoming traffic that matches the criteria of this rule
will be redirected to that IP address.
•
If you type a range of addresses, incoming traffic will
be redirected to any available computer in that range.
This option would typically be used for load
balancing, whereby traffic is distributed among
several redundant servers.
4. In the Global Address From / To fields, type the public IP
address assigned to you by your ISP.
If you have multiple WAN interfaces, in both fields type the IP
address of the interface to which this rule applies. This rule
will not be enforced for data that arrives on WAN interfaces
not specified here.
If you have multiple WAN interfaces and want the rule to be
enforced on a range of them, type the starting and ending IP
addresses of the range.
5. Enter a destination addresses (or a range) and port ID (or a
range) as criteria for incoming traffic.
Depending on which other fields you define in this step,
incoming traffic that meets this criteria will be redirected to the
address(es) specified in step 3 (assuming it comes through
the interface specified in step 2).
•
Enter a starting and ending IP address in the
Destination Address From / To fields if incoming
traffic destined for these addresses should be
redirected.
You can also enter a single address in both fields.
•
Enter a starting and ending port number in the
Destination Port From / To fields if incoming traffic
destined for these port types should be redirected to
the address(es) specified in step 3. Or, enter the
same address in both fields.
6. If the publicly accessible LAN computer uses a
non-standard port number for the type of traffic it receives,
type the non-standard port number in the Local Port field.
The basic rule: Performing 1:1 translations
The basic flavor translates the private (LAN-side) IP address to a
public (WAN-side) address, like napt rules. However, unlike napt
rules, basic rules do not also translate the port numbers in the
