Here's the output of 'tc qdisc show' after running the following script (snippet that handles cake-autorate):

					# probably should restart cake-autorate here, since the VPN has changed...
					# Check if cake-autorate is running, and what it is currently using for it's ul_if value:
					if [[ "$(service cake-autorate status)" == "running" ]] && [[ "$DOYOULIKECAKE" == "1" ]] && [[ "$RELOADCAKE" == "0" ]] ; then 
						echo "Cake is running, Cake selector is enabled, VPN has NOT changed: Do nothing."
					# else if the VPN has changed:
					elif [[ "$(service cake-autorate status)" == "running" ]] && [[ "$DOYOULIKECAKE" == "1" ]] && [[ "$RELOADCAKE" == "1" ]] ; then
						echo "Cake is running, Cake selector is enabled, VPN has changed: restart Cake-autorate" | tee -a "$log_file"
						service cake-autorate restart
						RELOADCAKE="0"
						sleep 2
					elif [[ "$(service cake-autorate status)" == "inactive" ]] && [[ "$DOYOULIKECAKE" == "1" ]] ; then
						echo "Cake is NOT running, and cake selector in this script is enabled"
						echo "service cake-autorate start"
						service cake-autorate start
						# Config.primary.sh in /root/cake-autorate/ will pull the current VPN connection /tmp/currentvpn.txt, and operate on that.
						sleep 2
					elif [[ "$(service cake-autorate status)" == "running" ]] && [[ "$DOYOULIKECAKE" == 0 ]] ; then
						echo "Cake-autorate selector DOYOULIKECAKE turned OFF. Cake running. Turning off/stopping:"
						echo "service cake-autorate stop"
						service cake-autorate stop
						sleep 2
					elif [[ "$(service cake-autorate status)" == "inactive" ]] && [[ "$DOYOULIKECAKE" == 0 ]] ; then
						echo "Cake-autorate selector DOYOULIKECAKE turned OFF. Cake not running. Do nothing."
						sleep 2
					fi # finish starting Cake-autorate for current connection, if selected, or terminating otherwise.

The above cake-autorate snippet is running in an updated version of the https://openwrt.org/docs/guide-user/services/vpn/wireguard/extras#connection_probevpn_automation_failover_script

Requires modification of the /root/cake-autorate/config.primary.sh:

# read -r CAKEWAN < /tmp/currentvpn.txt
# dl_if="ifb4${CAKEWAN}"
# ul_if="${CAKEWAN}"

Does that look correct?

I ask because the 'tc qdisc show' output looks strange to me. It looks like cake is working on multiple protonvpnX adapters, when in this case it should only have an dl_if of 'ifb4protonvpn4' and a ul_if of 'protonvpn4'. Here are the prepared interfaces in Openwrt: protonvpn, protonvpn2, protonvpn3 and protonvpn4. I've manually switched the active vpn interface to protonvpn4, via STOP protonvpn, and RESTART protonvpn4, in the web interface Luci, without the wan-watchdog.sh running. Then I re-ran wan-watchdog in testing mode, where it only runs once and will not reboot the router. It correctly detected the change of the active VPN, and restarted cake-autorate.

From 'tc qdisc show', it seems to me that part of the wan-watchdog.sh may need additional code, to tear-down any of the other unused protonvpn interfaces (protonvpn,protonvpn2 or protonvpn3), before restarting the cake-autorate service on the active one (protonvpn4).

It would not only look cleaner when querying 'tc qdisc show', but the current situation may not be working correctly. That's why I ask here.

Uh oh!

Uh oh!
