Figure 8-7 Nat Rule: Add (Rdr Flavor) - ZyXEL Communications Prestige 623 series User Manual

Step 1. In the NAT Rule – Add Page, type in a unique Rule ID, and select RDR as the Rule Flavor.
Step 2.
Select the interface and, if desired, a protocol that this rule applies to.
Step 3. 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 4 and 5 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 computers or assigned dynamically using DHCP, as discussed in
Configuring Dynamic Host Configuration Protocol chapter).
Step 4. In the Global Address From and Global Address To fields, type the public IP address
assigned to you by your ISP.
