I think as long as one side of the tunnel is not doing NAT then you would be okay. For a while I had an IPSEC VPN going between my cloud server and my home desktop so that I could access my home desktop remotely and it worked well.

Many thanks for all the suggestions, folks. I think I will have a play around with egre(4) and etherip(4) paired with iked(8) first and then move on to OpenVPN if all else fails. I will try to simulate the network layout with vmm(4) and hopefully report back in a few days. On Wed, 1 Apr 2020, at

You could also consider using etherip(4). I think the etherip(4) interface might be more NAT tolerant but I am not really sure.
