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

Exact same situation, but I have had issues with the shitty ISP box resetting itself on an outage and simply not forwarding traffic from the open ports to my router with a static IP. It would just say "no" and I had to change the static IP on the ISP box and reboot everything and then it would work fine. It has been fine for 3-4 months without needing anything, but sometimes it is annoying.

I'm not sure if its applicable for you or if you are aware but duckdns really helps with this problem. I've moved three times since and have never worried about ip addresses.

I think you are referring to Public IP? The person above was talking about the static Local IP.
