I thought about UPNP, which from what I remember allow any device to open port in the router. There appears to be an UPNP IGD server in the router, I can find it using tools like this one : https://sourceforge.net/projects/upnp-portmapper/ , and I can add ports to it. But it doesn't seem to be working either, at least with the settings I've set :. Source: 5 months ago
