OK. Here is my config. I compared it to my old, working config from last year and the NAT config used the PPPoE interface and not the physical interface, but I tried both to no avail.
Thanks again for your help. I have been going crazy over this. I work for an ISP and I have a many years experience with Cisco & Juniper routers. I also used to program Mikrotik routers in the past, so I ain’t an idiot (though I feel like one now!).
