Static IP, CGNAT, help and advice

Plex Media Server Remote Access
1

Hi

Just looking for some advice on remote access. Many of the posts I’ve read so far, start off with me understanding, but i quickly get out of my depth.

Background:
I run plex media server on a synology nas drive, running the latest dsm (7.2)
I have an orbi modem / router.
Plex remote access works (for a few mins) then stops.

Based on what i have read so far in help posts and blogs I have:
-Given the nas drive a fixed ip address reservation in orbi
-I have gone into the nas drive control panel, and set the network interface to the same fixed ip address that i reserved in orbi.
-I had Upnp turn on in orbi but after reading how insecure it was i’ve turned it off.
-I have set up port forwarding inside orbi from 32400 to the fixed ip address of the nas drive
-I have turned remote access on in plex.

After all that it still didnt work, back to the posts and blogs and I’ve realised my isp is using cgnat.

Reading a bit more and given i’m a technical novice, it seems like asking my isp (2 degrees in nz) for a static ip address is the easiest way to resolve the issue. Other options seem a bit too complex.

My questions and therefore the help i’m looking for?

  • do i just ask for a static ip address, thats it? No extra requests or details?
  • Is asking for that enough to bypass cgnat?
  • Once i get it a static IP address what do i do with that info? Ie do i put it in plex somewhere? In the orbi, the nas? All 3?
  • do i need to undo anything i did before, once i get the static ip, for example do i have to remove the port forward or turn upnp back on etc?

Lots of posts, suggest a static ip will help remote access but they dont seem to offer much advice on how to apply that solution. Any insights, advise, tips, recommendations appreciated. Thanks.

You don’t need a static IP address, but a „publicly routable IPv4 address“.
Your ISP might still opt to offer you a static IP address — this will also work, but it usually comes at a price.

That’s purely on their side. No additional changes needed on your end.

As a side note:
If you’ve configured an IP reservation for the NAS in your router, you don’t need to hardcode that on the NAS itself. The NAS should obtain its local IP from the DHCP server of your router (where it’s set to use a static reserved IP). This won’t be an issue for you now but can turn ugly if you ever get a new router that uses a different IP range (e.g. 10.0.x.x instead of 192.168.y.y). If your NAS insists to use an IP of the old range, other devices might consider it to be outside your home network.

Thanks Tom

And if i can get a IPv4 address, whst do i do with that info? Or once i have it, does remote access just work?

A „publicly routable IPv4 address“

Nothing for you to do.
This is about the public IP / WAN IP assigned by your ISP to your router. That should overcome the CGNAT issue without further intervention from your side (assuming there’s no other issues with your config)

Thank you, will call them tomorrow and then post an update.

Thanks Tom. A call to my ISP looks to have finally fixed it. Appreciate the advice.
