"Two network layers?!?"
Hah, yes and in the real world we do far weirder things than that. VXLANs running over [whatever], OpenVPN inside IPSEC and then ssh or RDP inside that. Obviously you don't do all of that routinely but I've seen some crazy shit to work around something or link up odd setups. I have seen a triple nested VPN: IPSEC within IPSEC and OpenVPN inside. I'm sure many here will have seen similar or worse.
