How can I test if a VPN connection is working on my DS214?

So I *think* I’ve set up a VPN connection to connect all traffic going to/from my DS214…

The question is … how can I verify that? Is there a browser hidden inside the DiskStation?

Instead of testing connection and monitoring it configure your firewall to prevent your nas from connecting to anything but your VPN provider endpoints. Then if the vpn connection is dropped it just loses connectivity as opposed to continuing to use your providers connection

Answering your question — curl ipinfo.io would be the simplest

well what does it report for your external IP? Control Panel, external access - does it report your normal public isp IP, or IP from your vpn provider?
