meshboi currently has some logic to ensure that the peer's firewall is open for inbound connection from other meshboi peers:

However, there currently is no mechanism to ensure that the firewall is kept open for the duration of the connection between the peers. This leads to firewall/s timing out the opened port and the connection between two peers dropping, if there is no traffic between the peers (for ufw this seems to happen after ~10mins or so).

Similar to the heartbeat that is sent to the rolodex, to ensure the NAT mapping stays open

meshboi should also send a periodic heartbeat to all peers to ensure that its firewall ports remain open.
