DESCRIPTION
Network Address
Translation (NAT)
Network Address Translation (NAT) allows the translation of an Internet protocol address
used within one network (for example a private IP address used in a local network) to a
different IP address known within another network (for example a public IP address used on
the Internet).

NAT Loopback
NAT loopback allows local users to use a domain name to access a server on the local
network. A packet sent to the public (WAN) IP address is always forwarded to the default
gateway (the LTE5366). With NAT loopback enabled, the LTE5366 uses the WAN interface’s
IP address as the packet’s source address and treats the packet as if it came from the WAN
interface. The packet then can be forwarded to the local server according to the port
forwarding rule.
