Access to Fan network from outside (LXD 3.14)

Hi,

I’m running LXD in Vagrant (VirtualBox provider). I’ve set up a cluster with Fan networking and it seems to work fine. Containers start on the cluster, and I can access the containers from within the Vagrant VMs, and I can ping my laptops IP from within the LXD containers inside the Vagrant VMs.

I can’t access or ping the containers from my laptop however. How would I go about letting my laptop access the containers running inside the Vagrant VMs?

Also, can I configure LXD to use some other IP range than 240.x.x.x for the Fan network?

You can configure the overlay subnet through the network configuration.
fan.overlay_subnet I believe.

As for accessing the Fan overlay from other systems, if you share the underlay, then you can install and configure ubuntu-fan on another system, manually configuring it for the same overlay and underlay as is used on your cluster.

Thanks for your reply @stgraber! How would I make the reverse possible? That is, how can I access my containers from my laptop, the same as my containers can access my laptop?

Best regards,

That’s the second part of my response, you’ll need to install and configure ubuntu-fan on your laptop so it can access the fan. This can only work if your laptop happens to be on the same underlay as the LXD cluster though.
