The BPI-R4 is great for use as a 10G WAN router if your ISP uses PPPoE since the network processing engine has hardware acceleration for it.

Unifi released the UCG-Fiber around a year ago that can also apparently finally handle it, but plenty of threads about slow performance with their UDMs since it's entirely done on the CPU [0].

I'm not the biggest fan of OpenWRT and would prefer something like OPNSense, but it's x86 only and good PPPoE performance isn't guaranteed either - need a CPU with good single core performance that costs more than the BPI-R4, or apparently virtualizing OPNSense allows it to process PPPoE with multiple threads.
