Topic: VPN drops every 15 minutes
I'm using "OpenWrt Chaos Calmer 15.05.1 / LuCI 15.05-149-g0d8bbd2 Release (git-15.363.78009-956be55)" on a WD MyNet N600 Router (yeah, I know, I have a D-Link DIR-860L on order) with OpenVPN and a NordVPN connection. It drops regularly - I wrote a script to monitor it and log the data as a band-aid (I could restart the connection a few seconds faster by sending OpenVPN a SIGUSR1 at the right time), and I noticed something weird:
The drop-outs occurred every 15 minutes. Not only that, but on the 00, 15, & 45 minutes of each hour - or just before that time. When the VPN started had no effect on this time at all.
I've checked the crontab, and found nothing whatsoever. What am I missing?
Thanks in advance!
