System Documentation

What problem does it solve?

This Skill diagnoses and resolves the Docker/LXD firewall conflict, enabling LXD containers/VMs to access the internet when running on a host with Docker.

Core Features & Use Cases

  • Firewall Conflict Resolution: Fix the well-known conflict where Docker's iptables FORWARD chain policy is set to DROP, affecting LXD network traffic.
  • Automated Fix: Automatically detect managed LXD bridges, add DOCKER-USER ACCEPT rules, and persist them with a systemd unit for reboot stability.
  • Use Case: If you encounter "Network is unreachable" errors in LXD containers or VMs, this Skill can help by accepting the LXD bridge in Docker's DOCKER-USER chain.

Quick Start

Run the command 'bash scripts/fix-lxd-docker-forward.sh' to apply the fix and restore internet access for LXD containers.
