All traffic halts when enabling CoDel

[shad0wca7]

I followed the guide in the presentation from the webinar delivered late 2018: https://www.netgate.com/resources/videos/pfsense-244-short-topics.html

Unfortunately when I activate and reset states, all traffic dies and the gateway monitoring shows 100% packet loss. I have 1 “true” WAN connection and 2 VPN’s as a virtual gateway.

Any idea what might be going on?
