Question:

Is the VPN domain nebula-66xxxxxx.d2ns-nbl.com pingable?

Answer:

The domain resolves to either the firewall's WAN interface IP or the uplink router's public IP. By default, the firewall does not allow ping (ICMP) from the Internet.
To enable ping, you need to create a security policy allowing ICMP traffic.
