Is it possible to establish an IPsec VPN between IPv4 and IPv6 ?
Any Use case?
Answer by PhoneBoy (Checkmates)
So you’re trying to establish a VPN where one endpoint is IPv4 and the other is IPv6? Pretty sure that’s not possible even with NAT.

That is not possible. These are 2 IP protocols and it makes as much sense as using SMB traffic to use an NFS share.
