Stop Memorising IPs: Domain Names for Your Proxmox Homelab with Tailscale App Connectors

Short summary

A detailed guide on configuring Tailscale App Connectors with dnsmasq to replace raw IP addresses with domain names for Proxmox homelab services. The setup uses one LXC container as subnet router, app connector, and DNS server. Includes ACL configuration, gotchas around nodeAttrs targeting, and systemd-resolved port conflicts.

• •Configure Tailscale App Connectors to route traffic to named domains instead of IPs
• •Run dnsmasq on the same LXC for local DNS resolution of .home.lab domains
• •Three key values (tag name, domain suffix, LAN subnet) must stay consistent across all config steps
