Rare project developers

imho i've an idea what happened: so the one-line installer wipes the linux 
networking completely,
from that point the linux's network stack only have a 10.255.255.1/24 ip and 
is hidden behind freerouter...
so imho it failed to bind to the requested ip:port pair from the config... 
moreover, since the linuxes
dont have the public ips anymore, the given setup you're trying to do is a 
double-nat case, but without
anything to punch through the nats, as these interface sockets should have 
direct visibility....
