How to reach a LAN device from WAN network using a PC located on remote site.

The Ewon gateway possesses two communication interfaces: a LAN and a WAN.

The Ewon gateway acts as a router and as such, embeds several features to allow interaction between the WAN, VPN, and LAN interfaces.

The NAT 1:1 is an extrapolation of NAT which maps an internal address (LAN) to an external address (WAN or VPN). For every entry inside the NAT 1:1, the Ewon gateway will create a new virtual IP address on its WAN or VPN interface. The LAN device associated with that entry then becomes accessible at this new virtual IP address.
