according to Big wish: NAT Traversal
what do you think about a RoSDK relay-server like this https://github.com/thinktecture/relayserver ?
A Proxy RoSDK-Server accessible from internet, with SSL-certificate and access-management for supplier. In background are many local RoSDK-Server, which hold an connection to this relay-server. So, no firewall-rules needs to be changed.
what is to do?
- it needs a new Ro channel-type for the connection relayserver <> Ro-Server behind the firewall
- the RoSDK-RelayServer route the client-requests to the several channels.
- for the first step, access-management and multi-supplier-support are optional
