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

You’ll be fine. In the past stuff like ftp and sip could get confused by double nat, but not so much today. And stuff like opening a port from outside to the inside needs some planning through double nat.

We run it in the office for years now and it is totally fine. We are in a building with multiple companies sharing internet and we wanted our own network within, so we are using double nat (internet modem and our switch).
