Here are the screen shots of the info
Apologies and thanks for help!!

They start with states during failover
Show the DNS error on web browser
(the is with Forwarder Mode off under DNS Resolver settings)

Then shows what happens after waiting for Frontier WAN to come back up

Ultimately would not fully connect and come back up untill full reboot of pfsense

@Gblenn
I have checked ALL for both

Is that correct?

[stephenw10]

Hmm, no DNS states shown there on states with ports starting with 53. You might need to filter differently to see that in the states.

I don't see the link state change in the logs there. Does it actually show the that when you reconnect the modem?

Yes that is correct, and I'm starting to think that ATT is actually blocking access to authoritative servers... If this is true you either have to stick to Forwarder mode, or ask ATT to stop blocking. I wonder if there is some setting you can change for your account perhaps?

On the fiber issue, there are a few things that stand out to me.

1. Gateway shows an IP but status is pending. So that IP is probably cached data in pfsense, the link is up (eth to frontier box) but pfsense has not verified the DHCP lease?

2. I notice you have IPv6 enabled on the fiber WAN. Could that cause issues? Try disabling it and see if that makes any difference when testing?

3. Have you tried pulling the fiber instead of the ethernet cable to pfsense? If that is possible to do?
   Keeping the physical link up on pfsense interface thoughout the test... If there is something on that side that isn't really working as it should?
   If you look at the dashboard instead of Status / Gateways, you will also see the negotiated settings for the interface. Does that seem ok, and is it the same before and after pulling and reconnecting the cable?
