  Hello :) This is a custom network configuration, and there's no native options in cPanel that will automatically configure/enable this setup. However, searching for a term such as "cPanel GRE Tunnel" on Google yields several results. Feel free to let us know if you encounter any issues with cPanel after configuring this. Thank you.

  That's an unsupported network configuration, but I believe the following third-party URL may help: CentOS " View topic - Boot script with iptunnel ifconfig iptables Thank you.
