Nat Mode Or Router Mode; Service Zone Network Interface - 4IPNET WHG315 User Manual

6.2.2. NAT Mode or Router Mode

Configuration Path:
NAT is the acronym for Network Address Translation which translates private IP
addresses for devices on the LAN side of a controller to routable IP before
forwarding into uplink network. Private IP addresses are invisible to devices or
routers on the WAN side of the controller, only the controller deploying the NAT
knows their corresponding translation. This mode not only protects users on the
LAN from being 'seen' by external devices but also solves the problem of limited
public IP's.
Router mode as the name suggests, is a network operating without address
translation in and out of the Controller. Router mode is selected when using public
IP or under circumstances where the downstream devices requires a routable IP
address to upstream routers.

Configuration Path:

out of range, enter the IP's in the Network Alias List and check Enable. Always
remember to click Apply upon completion.
