      I moved most of my routing duties to an x86 box, but I still terminate the PPPoE connection in my OpenWRT Netgear.

      The reason is remote unlock, so I don't have to stick a PPPoE client in my initramfs. Also I have remote access to a serial console via SSH.

      Actually I run two PPPoE sessions, and only one (v4) terminates in the Netgear. The other passes through (no NAT or extra routing hop on v6)

      Okay. I don't think I would have chosen that. To each his own. You have logical reasons, so no complaint here.

      I mean, my only other option was to stick a PPPoE client in my initramfs. Keeping all routing duties on the Netgear wasn't an option (perf).

      I get the preference. Why couldn't you put the PPPoE client & creds in the initramfs?

      I could, but that'd bloat my initramfs, and require retry scripts to ensure it stays connected, and complicate things.

      Also it still wouldn't let me have out of band serial access to this host like I do now with the double NAT trick.

      Okay. Why NAT internally? Why not route?

      Routing doesn't work on the inbound connections. I'd still need to NAT those.

      And once I'm doing that in the Netgear it means putting a bunch of per-service firewall rules in there I'd much rather keep in the x86 box.

          Basically you're proposing moving more duties/complexity back to the Netgear for the sake of avoiding a double NAT... why?

          My current setup basically lets me treat it as a black box, pretend my internal IP is public, and everything goes through except one port.

          Fair. I wonder if DMZ (DNAT everything) might help. Just trying to understand.

          Well that's what I'm doing right now. DNAT everything. (But also MASQUERADE plus the DNAT/SNAT hairpin rules).
