Configuring Network Address Translation

Follow the following instructions to add an RDR rule (see steps

1-4 under The NAPT Rule for specific instructions corresponding to steps 1 and 2 below):

1.Display the [NAT Rule – Add] Page, select [RDR] as the [Rule Flavor:], if necessary, and enter a [Rule ID].

2.Select the interface on which this rule will be effective.

3.Select a [Protocol:] to which this rule applies, or choose [ANY]. This selection specifies which type of Internet communication will be subject to this translation rule. You can select [ANY]

if the rule applies to all data. Or, select [TCP], [UDP], [ICMP], or a number from [1-255] that represents the Internet Assigned Numbers Authority (IANA)-specified protocol number.

4.In the [Local Address From:] and [Local Address 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 you specify in steps 5 and 6 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 to help ensure efficient network performance.

These addresses should correspond to private addresses already in use on your network (either assigned statically to your PCs or assigned dynamically using DHCP, as discussed in the Quick Start, Configuring Your Computers).
