I have two machines running docker. A (powerful) and B (tiny vps).
All my services are hosted at home on machine A.
All dns records point to A.
I want to point them to B and implement split horizon dns in my local network to still directly access A. Ideally A is no longer reachable from outside without going over B.
How can I forward requests on machine B to A over a tunnel like wireguard without loosing the source ip addresses?
I tried to get this working by creating two wireguard containers.
I think I only need iptable rules on the WG container A but I am not sure.
I am a bit confused about the iptable rules needed to get wireguard to properly forward the request through the tunnel.
What are your solutions for such a setup?
Is there a better way to do this?
I would also be glad for some keywords/existing solutions.
Additional info:
Ideally I would like to not leave docker.
Split horizon dns is no problem.
I have a static ipv6 and ipv4 on both machines.
I also have spare ipv6 subnets that I can use for intermediate routing.
