Tailscale Exit Node/Subnet Routers

Hi, I am running the pretty much default Tailscale configuration, with the following two parameters set. (See Screenshot) But unfortunately it doesn't seem to work. In the Tailscale panel I get the following error message: Unable to relay traffic This machine has IP forwarding disabled and cannot relay traffic. Please enable IP forwarding on this machine (https://tailscale.com/kb/1104/enable-ip-forwarding) to use relay features like subnets or exit nodes.

Use subnet routers to give devices outside your local network access to services within specific subnets. Extend your private network with Tailscale.

Should I just run the commands from the Tailscale Wiki on the machine? Or is more setup required, since it doesn't seem to work with the default settings unfortunately. Did anyone have the same problem by any chance?

I would suggest to try NetBird instead.

justmeOP•2mo ago

That worked well, thank you

Nicolas•2mo ago

How did you use Netbird? I'm curious to try it as well Install on host?

Nyarlathotep•2mo ago

I second this question. I want to try Netbird, too.

I installed it via https://community-scripts.github.io/ProxmoxVE/scripts?id=add-netbird-lxc

Excellent, works so nice And the latency seems way lower than with tailscale (on relay)

But on a Proxmox or a Tipi? Will have to make it work for Alpine anyway. Oh, btw, do you want my version of the Tipi install script? I didn't really change anything existing, but only added options for Alpine. Oh, OK, it doesn't seem to work with certain LXC containers. Yeah, I'm not going down that road. (Probably 😄 )

You can try with a custom app in Runtipi:

{
  "services": [
    {
      "isMain": true,
      "name": "netbird",
      "image": "netbirdio/netbird:latest",
      "environment": [
        {
          "key": "NB_SETUP_KEY",
          "value": "<SETUP KEY>"
        }
      ],
      "volumes": [
        {
          "hostPath": "${APP_DATA_DIR}/data/netbird",
          "containerPath": "/var/lib/netbird",
          "readOnly": false,
          "shared": false,
          "private": false
        }
      ],
      "hostname": "PEER_NAME",
      "capAdd": [
        "NET_ADMIN",
        "SYS_ADMIN",
        "SYS_RESOURCE"
      ]
    }
  ]
}

{
  "services": [
    {
      "isMain": true,
      "name": "netbird",
      "image": "netbirdio/netbird:latest",
      "environment": [
        {
          "key": "NB_SETUP_KEY",
          "value": "<SETUP KEY>"
        }
      ],
      "volumes": [
        {
          "hostPath": "${APP_DATA_DIR}/data/netbird",
          "containerPath": "/var/lib/netbird",
          "readOnly": false,
          "shared": false,
          "private": false
        }
      ],
      "hostname": "PEER_NAME",
      "capAdd": [
        "NET_ADMIN",
        "SYS_ADMIN",
        "SYS_RESOURCE"
      ]
    }
