How to make in openvpn, when routing changes, it restarted?

Question

FreeBSD

Good day!

Guys, this is the challenge.
When the routing table was changed, the
OpenVPN Service accepted and rebooted.
How can it be done with a script?

Answer 1

Get the routing table, write it to a file
In the crontab, add a script to run every - how many minutes you need there, which:
1. Reads the routing table.
2. Compares with the previously created file.
3. If there are changes - writes a new file with routing, restarts openvpn, if not - ends the script.
