Set the IP Address by Using
Network Address Translation
(NAT) NAT translates one IP address to another IP address via a NAT-configured
router or switch. The router or switch translates the source and destination
addresses within data packets as traffic passes between subnets.
This service is useful if you need to reuse IP addresses throughout a network.
For example, NAT makes it possible for devices to be segmented into multiple
identical private subnets while maintaining unique identities on the public
subnet.
If you are using NAT, follow these steps to set the IP address.
1. In the IP Address field, type the IP address that the controller will use.
This is usually the IP address on the public network when using NAT.
2. Click Advanced to open the Advanced Ethernet Settings dialog box.
3. Check the checkbox to indicate that this module and the controller
communicate through NAT devices.
4. Type the Actual module address.
TIP If you configured the IP address using the rotary switches, this is the address
you set on the device. Alternately, the Actual module address is the same
address shown on the device's Internet Protocol tab.
