Hi
It will just be to monitor your infrastructure from a security protective.
I don't see the advantage of aci here but i would rather use a VPN connection that could be L2L vpn or dmvpn config. You can use whatever technology encapsulating layer 2 over layer 3 like vxlan, l2tpv3, .....
Can you give me details why you don't to use vpn? I mean this is the way you go when you want someone external to access your corporate network.
Thanks
Francesco
