What do they allow?

If you are talking about donations, then: Crypto works always and for everyone
If you are talking about the GUI, then this script could conveniently view the settings, status.
in Domain-based VPN Routing Script, I would like to change settings through the web interface (add and remove domains, set which vpn interface to use)

I need to get back into Crypto...I had some up until last year but yes that's what I was referring to because I know things are restrictive where you are so was curious. As far as UI I'm going to be working on an SSH UI for WAN Failover first so it can get integrated with amtm and then consider something like that for Domain-based VPN Routing.If you are talking about donations, then: Crypto works always and for everyone

Not sure how that happened but my guess is this. The output of the pings are written to a temporary file in memory under /tmp and the function is set to wait on the ping commands to finish before reading the output but somehow the write may have not been finished when it was being read.

More cosmetic stuff to consider @Ranger802004 when you get around to noodling on the next beta ...
I think this one could well be related to the last bug you squashed for me prior to releasing 1.5.6 maybe?
I did a quick Reboot of my Secondary WAN device, a 4G LTE USB Stick, using it's own GUI, so no Failover/Fallback, just "loss' of backup capability for a minute or so.
All handled properly by wan-failover / vpnmon-r2, but the emails are slightly incorrect as below, it's taking the Active IP and Gateway addresses from the Secondary but gets everything else right.
Let me know if you want logs?
Also, the reason I was rebooting the USB stick was that this morning when I was checking I couldn't get to it's web interface on 192.168.2.1, even though I could ping it.
Had to connect separately to it on its own Wifi in order to login and reboot it.
Was definitely working yesterday via the Asus router and suddenly stopped for some reason - maybe not related at all to wan-failover.
I assume the reboot of USB stick makes your script re-impose the routes? Don't know if there is something else going on ... will monitor for a repeat.

The router deletes the rules/routes when an interface is dropped and defaults things back to WAN1 so I just have to find what condition it is and force it back. Logs will help

So I'm in the middle of developing first beta for v1.5.7 and I'm trying to make sure I am thinking of all of the requests I received for enhancements (not fixes). So far I've incorporated these 2 for the next build but if you have any additional requests please post here and I will see what I can do to implement them into the script, thank you!
- WAN0 and WAN1 can be specified to have QoS Enabled or Disabled during Failovers.
- WAN0 and WAN1 Packet Size can be specified seperately in Configuration File.
- Custom Log Path can be specified for Monitor Mode using CUSTOMLOGPATH setting in Configuration Settings.
- WAN0 and WAN1 can be specified to have QoS Enabled or Disabled during Failovers.

I had the same thing right now. I haven’t checked for a long time how my devices are connected to wan1 (ethernet, not usb) and they were also all unavailable for entering the web interface. Restarted from physically and everything earned. True, I set up something in the router (the same thing for all three), so for now let's write it off as a glitch.

Confirmed this is working, thanks @Ranger802004.
Also did a quick remote reboot of my 4G USB stick to simulate a WAN1 outage, that went OK. Noticed reduced amount of info on the notification emails? No more IP/Gateway/Interface? Deliberate I assume?

No it should be there just grabbing it a different way to ensure accuracy, do you have logs you can send?

Thanks and slapped this beta in for testing, specifically for this feature.
Observation
- QoS is only disabled on Failover and not reconfig/restart of the script. My expectation is that on reconfig/restart the QoS settings/toggle should be enabled/disabled based on configuration file. Thus, for WAN0 I had to manually disable QoS. Trending in the right direction as usual @Ranger802004
