ip router backborn coupler

[mellotron]

I use wiser as a web server to control the knx equipment on two remote sites and on the chance of the sites I have an IP router from the Intera and Enertex brands. on the local network everything works fine but when I connect to the internet I cannot control the equipment on the two sites. I put the wiser in tuning mode but unfortunately with this mode I do not have the status feedback from the remote site and with the other mode the wiser does not communicate with the remote site.
