lxd-docker-firewall-conflict skillA

lxd-docker-firewall-conflict is agent-read markdown (skill) from soulmachine/skills: Diagnose and fix the well-known Docker/LXD firewall conflict on a host running both. Docker sets the iptables FORWARD chain policy to DROP and accepts only its own bridges, so forwarded traffic from the LXD bridge (lxdbr0) is silently dropped and LXD containers/VMs get no outbound internet (the host itself is fine). Fix: accept the LXD bridge in the DOCKER-USER chain, then persist it with a systemd unit ordered after docker.service. Use when an LXD container has no internet or cannot reach archi.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add soulmachine/skills/lxd-docker-firewall-conflict@git:20260611.94752b4

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
