If the server is behind NAT, you can specify its endpoint with the `SERVER_PUB_IP` variable. If the endpoint is the public IP address which it is behind, you can use `SERVER_PUB_IP=$(curl ifconfig.co)` (the script will default to this). The endpoint can be an IP or a domain.
If the server is behind NAT, you can specify its endpoint with the `SERVER_PUB_IP` variable. If the endpoint is the public IP address which it is behind, you can use `SERVER_PUB_IP=$(curl https://ifconfig.co)` (the script will default to this). The endpoint can be an IP or a domain.
Other variables can be set depending on your choice (`SERVER_NIC`). You can search for them in the `installQuestions()` function of the script.
