Compatibility of Cloudflare WARP with LXC Containers

[mdgitcloud]

Hello everyone,

Is it possible to run warp-cli inside a Proxmox LXC container?

On a standard Debian installation, everything works flawlessly. However, I struggle to get WARP working in an LXC container. When I attempt to start WARP, the network disconnects, and the utility gets stuck in the "Connecting" state.

If WARP is compatible with LXC, I would greatly appreciate a step-by-step guide or a beginner-friendly script to make it work.

Thank you in advance for your help!

I had the same problem with my setup and found a solution in the tailscale documentation [https://tailscale.com/kb/1130/lxc-unprivileged] Unprivileged LXC does not have access to /dev/tun which cf warp and tailscale needs. I added the following to proxmox container conf and then cf warp tunnel succeeded.

lxc.cgroup2.devices.allow: c 10:200 rwm
lxc.mount.entry: /dev/net/tun dev/net/tun none bind,create=file
