I'm replacing a BT hub with a dedicated PC running OPNSense (a fork of pfsense). I've set up quite a few of these on non BT customers connections and had no problems.
I get everything to connect, using an HG612 modem with a PPPoE connection set up on the OPNSense box. It gets internet and everything seemed to work correctly.
Except the last line of text says the problem lies with Cloudflare rejecting the certificate. The OPNSense box is not configured to use Cloudflare for DNS. I asked the provider of the exchange email and they said they could not help. I am wondering if I need any particular DNS setting applied at the PPPoE connection.
I tried adding a new email address and the same message appeared rejecting the autodiscover info because of Cloudflare. It happens on every computer connected to the network when the OPNSense box is used.
I hope you have a resolution for this. I'm sorry if you are still struggling. If you would like to PM I can give you a call and try and figure out what is going on. Seems like a complicated issue, but I'm sure we can get to the bottom of it
