What is the wan address of the firewall device

Can’t be 10.10.10.0 as that is the network address,

Can’t be 10.10.10.1 as that is the LAN address of the Firewall (LAN of Firewall = gateway for all internal devices on the same network as the Firewall).

Can’t be found from Linux-2

It’s in the lab instructions.
