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:

1. Copy the below file to /etc/gl-switch.d/tailscale.sh and replace the exit_node_ip value with your exit node ip address.

2. Make sure to set the execute bit on the new file: chmod +x /etc/gl-switch.d/tailscale.sh

3. Depending on version:

   4.8.0 and above:
   Copy/write the switch-button file below to /etc/config/switch-button

   4.7.4 and below:
   Go to System -> Toggle Button Settings and choose Tailscale (On/Off) in the dropdown and Apply

switch-button

# /etc/config/switch-button

config main
        option func 'tailscale'

tailscale.sh

#!/bin/sh
# /etc/gl-switch.d/tailscale.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

Has anyone tried using the side switch to toggle between 2 different exit nodes? I gave it a quick go with the older firmware version but didn't get it fully working before having to turn attention to a different project.

@ghzgod do you think it would be possible to modify your kill switch to instead automatically redirect to a backup exit node if the primary drops?
