Disable or limit the check whether the prover listener port is open

💥 disable or limit the check whether the prover listen port

We run prover in home network, and the operator just disconnect the prover because we can not set the NAT or port forwarding in our router. As the help from @HarukaMa, we disable the check for port in operator and prover. Indeed, it not easy to do the NAT and port forwarding in home network, so we suggest disable the check for prover.

In addition to this, there used to be a proposal to use UPnP for automatic port forwarding for testnet1. I'll try to revive it for testnet2 shortly.

I just filed https://github.com/AleoHQ/snarkOS/pull/1575 that should aid port forwarding with UPnP-enabled routers.

ok, it should be an option logic, not default logic

Consider whether to delete this lines?
I run node behind NAT in home. ISP give me a LAN IP (such as 10.0.0.1).
My node listens 0.0.0.0:4132. but remote is x.x.x.x:9157. It can not be connected successfully with this lines. but I'm not sure if it will have some ploblem.

@wanyvic while this suggestion is being considered, have you tried the workaround described here?

[wanyvic]

I had tried https://github.com/AleoHQ/snarkOS/pull/1575, The problem still exists.
