Usage

usage: p2p-port-forward [<flags>]

Flags:
      --help                   Show context-sensitive help (also try --help-long and --help-man).
  -n, --network="8056c2e21c000001"
                               zerotier network id
  -f, --forward-port="22"      port to forward (in listen mode)
  -a, --accept-port="2222"     port to accept (in connect mode)
  -u, --use-udp                UDP instead of TCP (TCP default)
  -c, --connect-to=CONNECT-TO  server (zerotier) ip to connect
      --version                Show application version.

On host1 (where the service or any port should be exposed)

p2p-port-forward [-n 8056c2e21c000001] [-f 22]

On host2 (where we want to access the port)

p2p-port-forward -c <server-ip-from-output-of-server> [-a 2222]

Then connect to port 2222 on host2, to reach host1:22. Ex:

ssh -p 2222 user@localhost
