Screenshot of Ewon device's web interface

Specify here the IP address of the LAN device you want to reach and click Connect.

The Ewon device will then redirect all incoming requests of the WAN (or VPN) address and forward it to the specified address on the LAN side.

To allow disabling the TF feature, the Ewon device forwards all ports except its secondary HTTP port (by default set to TCP:81)

Use this secondary HTTP port to access the Ewon web interface (http://Ewon-device-IP-address:81/index.shtm) to disable the TF feature.

Just click on Clear transp. forwarding to disable forwarding of TCP requests.
