Tailscale script for GL-iNet Beryl AX side switch

This script allows you to toggle tailscale settings using the physical side switch on the GL-iNet Beryl AX.

To install, copy the below file to /etc/gl-switch.d/tailscale.sh and replace the exit_node_ip value with your exit node ip address.

Then go to System -> Toggle Button Settings and choose Tailscale (On/Off) in the dropdown and Apply

tailscale.sh

#!/bin/sh

action=$1

if [ "$action" = "on" ];then
  enabled=true
  lan_enabled=false
  wan_enabled=true
  exit_node_ip="{{ REPLACE WITH YOUR EXIT NODE IP }}"
elif [ "$action" = "off" ];then
  enabled=true
  lan_enabled=false
  wan_enabled=true
  exit_node_ip=""
else
  echo "Usage: $0 [on|off]"
  exit 1
fi

curl -H  'glinet: 1' -s -k http://127.0.0.1/rpc -d "{\"jsonrpc\":\"2.0\",\"method\":\"call\",\"params\":[\"\",\"tailscale\",\"set_config\",{\"enabled\":$enabled,\"lan_enabled\":$lan_enabled,\"wan_enabled\":$wan_enabled,\"exit_node_ip\":\"$exit_node_ip\"}],\"id\":1}"

sleep 5

Thanks for posting this! I modified it to turn Tailscale completely off or on (with an exit node). A few things:

• For some reason, the GUI hides the WAN/LAN enable setting when custom exit node is enabled. This seems like a bug in the GUI maybe? I notice that if they are enabled/applied, and THEN you configure a custom exit node, they would remain on the last configured state - so I don't know why the GUI is hiding those options. I think a long time ago, when using an exit node, the WAN/LAN settings did not apply on the Tailscale side of things, but to my knowledge, the functionality to expose at least the LAN side optionally when using an exit node was added to the Tailscale feature set
• Be sure to set execute rights on the tailscale.sh file after copying to the router

Mind sharing your script?

I tried using this on the Slate-AXT 1800 but didnt seem to work, should this work across all GLiNET units with the toggle switch or do they have different saving of files for the toggle switch?
