      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?

      You ask a fair question. One that I can't readily answer. Thus I'm re-evaluating.

      Generally, NAT, is considered less than desirable. NAT can complicate things like tracing packets.

      Let's not forget the implications that NAT has with questionable protocols.

      Though two or more NATs is probably negligibly worse than a single NAT.

      That's the thing. Nothing really sees/notices the NAT in the middle except the two routers on either side.

      I should post a diagram of my home net sometime. It's physically very simple, and logically rather complex.

          There are... 7 SSIDs, 9 VLANs, 3 network namespaces, 3 VPNs involved. Oh, and transport mode IPSec.

          2 SSIDs, 14 (?) VLANs, 11 (?) namespaces. ? because: do veth pairs count as VLANs? Does the main NS count as an NS?
