I has configured an AllStarLink node in an instance of Google Cloud Platform (Debian 9 Stretch). The installation was quick and works normally.
The link is listed in All Star Link nodes list and appears as active.
The problem is that I can’t reach it with DVSwitch Mobile client. A suggestion was create a firewall rule to open port 4569 (IAX) but the node still unreachable.
Curiously, if I configure the DVSwitch Mobile client with USRP protocol, the client is registered but testing with 9990 parrot, I can’t listen my voice.
What I need configure to put 100% operative this node?
