How terrible is double NAT? really? (self.selfhosted)

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

Can you set the ISP box to designate your router as DMZ (de-militarized zone)? Your router needs to get a static IP from the private subnet defined by their router, then you mark that IP as DMZ in their router's settings.

It's not technically the same as bridge mode, the ISP box continues to act as a router but also exposes your router fully to the internet so you can mostly ignore theirs afterward.

Yes, that's essentially what I did.
