Forwarding random port with upnpc

[Neylix]

Describe the problem you discovered

In previous implementation, while forwarding to port 0, the router was redirecting a random port. But since we use miniupnpc, we cannot anymore forward the port 0, so we cannot open a random port automatically.

Describe the solution you'd like

We have 2 options :

• Consider using an other tool for port forwarding like https://github.com/benoitc/erlang-nat if this implementation is working well it would be better than having a upnpc programm compiled in C and opening a random port using 0 works in this lib
• Determining a list of port possibility and taking a random number until the port opening is working

Update

'https://github.com/benoitc/erlang-nat'
With the upnp capability enabled or disabled, my local network is inoperable with this nat lib operations, and I am unable to connect to other nodes.

Proposed solution:

1. Continue with option nb 2,

2. CLI to ask user(step by step like in aebweb cli) for input for env variables. else they can ignore and move with default
