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.
Awesome! I’m glad I could help. Good luck! I’ve been spending quite a bit of time figuring out how to get this to run alongside other services. I think I just need to add an extra iptables rule to ignore port 443 so https requests will go through traefik first.

Wow this may have been the missing piece to get my setup working. If I manage to do it will send you an URL to a git repo.
