How terrible is double NAT? really? - eviltoast

Hi,

I’ve been trying to work out my network architecture with the pieces i have today:

  • isp box with 10gig dac downlink, 4 ssd bays
  • pfsense box with dual 10gig dac card
  • switch with 10gig dac uplink and multi gig rj45
  • main proxmox host
  • other devices (laptops, iot…)

ive ran into a dilemma regarding switching my isp box to bridge mode:

  • if i do, i lose wlan and nas capabilities
  • if i dont, i have to contend with double nat

i’m sure that eventually i will get an ap (maybe unifi) and a dedicated nas (either home built or something like synology or asustore), but for the moment, i want to keep cost down and gradually add new pieces

i was wondering if double nat is of huge performance and maintenance implications, or if i would be okay running this setup for a few months until i get to add an ap and nas?

thank you

    No issues with double NAT. I even had a setup with an internal and external net, and the provision that any network link originating from (not passing through) the outer NAT router would raise an alert on the inner NAT router - which would simply switch the outer NAT router off.
