I finally decided that I wanted to be able to externally access some of my Docker containers from outside of my local network. I don’t want to deal with the security hassle of exposing ports on my router, so I decided to go with Tailscale.
All of my container web services are run through traefik and are accessed using hostnames I set up on my DNS server. How would I go about accessing the different web services externally since the hostnames don’t resolve?
Set tailscale to use your dns server to resolve your services (or all traffic if you prefer). Assuming your dns server is on 100.x.x.1:53, then put 100.x.x.1 as a nameserver.

I set that up, but the issue now is that my DNS server is replying back with the private IP, which is not accessible from tailscale.
EDIT: Figured this one out. Need to advertise the routes from one of my machines. Set that up and I am good to go now. Thanks!
