@johnpoz - thank you for the suggestions of double NAT, tho I think it is not the optimal solution as I require wireless. Yes, the ISP router is very basic, but works out of the box with wifi 6 and I have a stable fast connection...If I didn't have to deal with MAP-E, I would put the ISP modem (yes, vdsl modem in 2023...) in bridge mode, hook up the netgate 2100 to it and use the ISP router as a simple access point for wifi.
