1= Open the /etc/rc.local file:
nano /etc/rc.local
2= Copy and paste the following commands into the file, replacing the placeholder IPs with your external and Iranian IPs:
#!/bin/bash

Now both of your servers are connected, and you have a local IPv6 address:
IP Kharej: 2001:470:1f10:e1f::2
IP Iran: 2001:470:1f10:e1f::1
