Switch Wireguard connection on / off via the digital input RUT 241

[Walle]

Hi folks,

I hope you can help me. I would like to switch my Wireguard connections off and on again via the digital input.
Is the digital input 0 = Wireguard Connections switched off
Is the digital input 1 = wireguard connection switched on

How exactly do I have to do this? Can you help me with this?

Many thanks in advance
Walle

Hello,

To toggle WireGuard connections on and off based on a digital input, you can leverage the I/O Juggler feature on your router and configure it to execute scripts depending on the state of the digital input. Here’s an example guide:

---

Step 1: Prepare the Scripts

1. Access the Router’s CLI
   Log in to the router’s Command-Line Interface (CLI) using SSH or directly through a terminal.
2. Navigate to the /etc Directory
   Run:

cd /etc

3. Create the Scripts

• WireGuard ON Script (wgon.sh):
  Create a new file using vi:

vi wgon.sh

Press i to enter insert mode and add the following:

#!/bin/ash
uci set network.<wireguard_interface>.disabled='0'
uci commit network
/etc/init.d/network restart

After making changes, hit Esc and write :wq and press Enter.

Replace <wireguard_interface> with the name of your WireGuard interface. You can find this using the ifconfig command or in WebUI (Services → VPN → Wireguard)

• WireGuard OFF Script (wgoff.sh):
  Similarly, create another file:

vi wgoff.sh

Press i and add:

#!/bin/ash
uci set network.<wireguard_interface>.disabled='1'
uci commit network
/etc/init.d/network restart

4. Make the Scripts Executable
   Run the following commands to make the scripts executable:

chmod 777 wgon.sh
chmod 777 wgoff.sh

---

Step 2: Configure I/O Juggler

1. Access the WebUI
   Log in to the router’s web interface.
2. Navigate to I/O Juggler
   Go to Services → Input/Output → I/O Juggler.
3. Create Actions

• Go to the Actions tab and add two new actions:
  • Action 1 (WireGuard ON):
    • Name: e.g. wg_on
    • Action Type: Script
    • Script File: /etc/wgon.sh
  • Action 2 (WireGuard OFF):
    • Name: e.g. wg_off
    • Action Type: Script
    • Script File: /etc/wgoff.sh
      
      
      
      
      
      
      
      

4. Set Up Triggers

• Go to the General tab and add two instances:
  • Instance 1:
    • Input: Specify the digital input (Input (3)).
    • Trigger: Rising
    • Add action: wg_on
  • Instance 2:
    • Input: Specify the same digital input.
    • Trigger: Falling
    • Add action: wg_off
      
      
      
      
      
      
      
      

5. Save and Apply Changes
   Click Save & Apply to finalize the configuration.
