About

Check if a pfsense VPN tunnel is UP and alert when it's DOWN.

Getting Started

Prerequisites

• pfsense 2.7.2
• Uptime Kuma

In Uptime Kuma create a Push Monitor and note the Push URL.

Installation

Download script to your pfsense home directory

wget https://github.com/hhanzo1/check-tunnel/blob/main/check-vpn-tunnel.sh
chmod +x check-vpn-tunnel.sh

Update the script with the tunnel name (ie. ovpnc1 or ovpnc2) and the Uptime Kuma Push URL.

Usage

Run the script manually to check it is working as expected, then scheduled via cron.

Enable the check script

# Run every minute
* * * * * /home/[USERID]/check-vpn-tunnel.sh

If the Push URL does not receive a HTTP request within the Heart Beat internal (default 60 seconds), an alert can be triggered.

Status and Uptime Uptime Kuma Badges can be configured.
