Originally created by @12nick12 on GitHub (Nov 29, 2022).

It appears the subnet is wide open for any hosts on the VPN. For example I have host A (windows) who is able to connect to any device behind subnet router (linux). The ACLs work for the subnet router so the windows device can't connect to that, but it's able to connect to the devices behind it. Is the expected?

  • Version of headscale used
    v0.16.4

    I don't have any ACLs opening the subnet routed network

Actually this was a fault of my own. I didn't realize I had 80/443 open to the world. Sorry about that. Great tool.
