NAT or Network Address Translation is a routing process where IP address information is translated to another IP address. Both addresses are typically of different subnetworks or segments in which Layer 3 devices such as the EDR-G902, EDR-G903 and EDR-810 series readily support.

NAT configurations for Moxa’s EDR series
What is a NAT?
Not to be confused with those pesky flying insects, GNATs. NAT or Network Address
Translation is a routing process where IP address information is translated to another IP
address. Both addresses are typically of different subnetworks or segments in which
Layer 3 devices such as the EDR-G902, EDR-G903 and EDR-810 series readily
support.
Types of NATs typically use
N:1 NAT
This is a very popular NAT process that is encountered all the time,
especially if your network utilizes the Internet connection.
N:1 NAT is when one (1) IP address translates to multiple (N) IP
addresses, very much how the Internet connection at home and small
office is set-up to do.
Port Forwarding
When you are in a N:1 NAT, you sometimes need to access services that
is located in the LAN side of the network (or the “N” part of the NAT)
which is hidden from the WAN or Internet.
Port Forwarding will associate a specific port or a range of ports from the
LAN and map it to another set of ports which can be different to the WAN.
This is usually used to forward ports in order to access Websites or FTP
servers from the LAN to WAN.
Port Forwarding can be too restrictive especially if you have multiple
similar services you would like to forward, such as HMI web interfaces
