IPv6 Monitoring stuck on pending

that is not the correct address for google dns, nor would it answer ping.. Nor would it matter if he has no gua to talk to it with.
Yeah.. quick draw here.. I assumed it was the gateway address.

But seems like what @stephenw10 is saying, is if the wan doesn't get a gua, that it should use an IP out of the lan side prefix as the source when dpinger wants to talk to the monitor IP if that is a gua..
Ah, no that's not what I'm saying.
pfSense will use a GUA address from some other interface for most traffic, pkg checks etc.
It specifically will not use it for dpinger though. dpinger always uses the interface address so that it get's forced via the correct gateway by route-to. So it fails to anything beyond the segment with link-local only on the WAN.

@stephenw10 thanks for the clarification.. But just curious why would it grab an IP from say lan to check for updates when it could just use the wans IPv4 address?
Maybe this needs a bit of a note in the docs? Or maybe a warning vs just "pending" about no gua to use to check the gua monitoring IP? Prob a note where you set the other monitoring IPs about needing a gua to check gua based monitor IP?

is there a way of of testing this?
Testing what? that you can't talk to gua from a link-local fe80 address? Or that you adding that :1 on the end isn't a live IP that doesn't answer ping or dns? ;)
link-local is for the local network only, they do not route.. So no there is no way to talk to a gua from a link-local out to the internet.. If the gui is on the same network then yeah ok might be able to do it.. But from a sane networking point of view it shouldn't

It could. It will prefer IPv6 though if it has a IPv6 route it can use. If you set 'prefer IPv4' it will use that.

Do you have another IPv6 Gateway? Diagnostics is using this if WAN6 is not up.
Missed this one. Not having IPv6 on WAN is not that common around here but in other places it seems to be.

@Bob-Dig - No, only one IPv6 Gateway on WAN
