I’ve VPN working, so I’ve one other the IP as my public IP. The VPN IP is detected by bitnodes, and I exploit iptables to create port ahead guidelines, since I am utilizing Linux working system.

I utilizing these instructions:

$ sudo iptables -t nat -A PREROUTING -p tcp -i [interface-name] --dport 8333 -j DNAT --to-destination [IP]:8333
$ sudo iptables -A FORWARD -p tcp -d [IP] --dport 8333 -m state --state NEW,ESTABLISHED,RELATED -j ACCEPT
