Goodcloud site to site - Unable to access clients

Hi. I have set up a site to site goodcloud network using 2 Mango V2. One has public IP; it is OK, it is working with 2 nodes (main node and node 1). I want to access a client (ie domotic web server) behind the mango in node 1. Is it possible and how to do that ? Thanks.

You need to add the IP of your domotic web server in your goodcloud S2S control pannel.

To add IP in Goodcloud S2S control panel, is it the add box in “Configure LAN IP and Access Control” ?

Yes it is. Pls try and see.

Thanks. But not understood and still not working after several attempts…

Can you draw a picture of your network topology?
