Guys please help, I am desperate, really

Plex Media Server Remote Access
1

Server Version#: 1.24.5.5173
Player Version#: 4.63.0
Synology: DS220+ (1 disk only in)
I have the latest version of Synology OS
Router: TP-LINK Archer C20 (connected primary to my Synology, I am using only one router, I have good internet connection, bc when I am connected to my Wi-Fi where is Synology connected then it is working I am able to watch my films in FULL HD, when I am on another Wi-Fi where is the same speed I can’t.)

I want to know how I can enable remote access in my Plex server, so I will be able to stream FULL HD, when I’m outside my home network where it is connected to my Synology.

IF U WANT TO KNOW EVERYTHING THEN READ IT IF NOT, UP THERE IS JUST SHORT VERSION OF IT.

I am lost guys, I don’t know how to enable that remote access, so I will be able to stream my films / serials in 1080p, now it’s just converting to 320p or 480p, when I am not connected to my local Wi-Fi where is connected my Synology NAS too. When I am somewhere else, I want to stream my films full HD on my notebook / mobile outside my home network. If u have any method how to fix it I would be grateful no cap, I have been looking for some fix for over 2 months :slight_smile: still didn’t find a solution :). My router is connected primary to my Synology NAS name of the router is TP-LINK Archer C20, I am not using double routers or something. If u want to know more info, no problem just ask I will answer immediately. Guys, thanks for your time. Hope u will fix my problem. (I have no problem with pc settings, so if I will have to set some IP addresses or something, I will do it with your help)

What does this mean in Mbit up/down?

In your settings under remote access you can click enabled - you should forward a port to the synology at this point.

This indicates that you can only connect indirectly

3

Speed - 40/40 I know that it can sound funny, but this is the best speed in our village

I tried to enable that remote access, but after 5 sec it drops to red, saying that it was unable to enable remote access

Why i wouldn’t be able to stream my content on Plex in HD, when others can?

Are you possibly behind some ISP that uses CGNAT (Carrier-Grade NAT) ? This also will prevent direct remote-connection…

Does you Internet connection have a true public IP ?
Can you check your router to see what you got on the “WAN” side ?
Please print the first 2 numbers of the IPv4 address.

I’m already a member of Plex yearly pass, thanks for your help, but I did exactly what u told me, but it didn’t fix my problem. Is there any chance that I would be screen sharing my desktop to you? (u can send me your discord or some socials, so we can speak privately) It would be the best solution for my problem if u don’t have problem with it. Thanks again for your time.

I don’t really know how to check, if IAM behind some ISP or something, sorry.

If I have true public IP? What does it mean? I contacted my Internet provider, and they said that my public IP is the same as others peoples what are under the same internet provider as I am. So basically it means that my friend have the same internet provider as me, so we checked if we have the same IP, and the answer is YES we have exactly the same IPs.

In the first image i covered my IP address, Subnet Mask and Gateway. If u want to know it, just tell me.

Thank you… 185.x.x.x is good enough. It confirms your ISP is not creating an artificial private network before it gets to you.

Please forgive my asking, so that it’s clear to me, do you have this?

So indeed, there is 2x NAT and that is the reason why (direct) remote connections do not work.
Ideally the 185.x.x.x would be on the screenshot of your home TP-LINK “WAN” section like you showed. But now it says 192.168.x.x (=RFC1918) so there is 1 additional router in the chain, which you seems not to control and THAT performs the final translation towards the public 185.x.x.x

So yeah, if you cannot find out who controls that other router carrying the 185.x.x.x the “direct remote access” will never work.

@jvanhambelgium

It’s possible to have double NAT. It just can’t be done automatically.

Two manual port forward entries, one in each router,
then tell PMS which ISP-side port to use,

and PMS is happy.

Yes, it’s a pain but it works (I’ve done it)

11

Sure 2x NAT is no problem if you control both devices, but I think its not the case here.
Could be some router from eg. appartment-block that provides shared Internet to several residents or something. Definitely something to investigate further if @marekmikan1999_gmail_com wants to get it working.

12

Agreed. Time to wait :slight_smile:

13

yes it can be as you described it. My router and modem + synology looks like this.

I don’t know if I’m so dumb at this, but I don’t even know what NAT means. I googled it, and It’s something about Network address translation. Likewise, I would be so grateful for some tutorial on how to exactly set my Plex with my Synology to working how it should be working. Mainly that remote access. I have no problem with screen sharing if someone of you have time to explain me and navigate me what to set and what to click.

@marekmikan1999_gmail_com

Yes, NAT == Network Address Translation

The idea is:

  1. You have one IP address on one connector (the Internet side)

  2. You have multiple IP addresses (your devices) wanting to share that internet connection.

  3. NAT, which is software running inside the modem/router, handles passing of traffic in and out AND keeping multiple devices from getting the wrong packets.

Example:

  1. TV wants to run the Netflix app. It reaches out to the modem/router. The modem router forwards the request AND keeps track of that request so that when the reply comes, it knows to send it to your TV and not your Laptop or phone.

  2. The same is true of every other device sharing the internet. NAT takes all those independent IP addresses and makes them appear as if only ONE device is connected to the internet (as seen from the outside) but keeps everyone separate on the inside.

The problem you have is that you have the TP-Link translating addresses AND the ISP translating those translated addresses again.

While traffic does flow, Opening a port for Plex can’t be done automatically. Plex (and UPNP) can only handle 1 device. The result will be that it can program the TP-Link but not reach to the ISP modem/router to program it too. That’s what we’d need to do manually.

What is that beige box? Is that your modem/router from your ISP ?

If so, what make & model is it? I’ll look up the user’s manual.

16

That small white box is a HALNY GPON ONT unit. So from there using UTP-copper to the T-LINK.
The ONT-box is a L2-device, so its for sure not responsible for the double-NAT.

Then basically I think you’re doomed in the sense that your ISP performs a NAT again on some central boxes. Nothing you can do about it (except change ISP) and Plex Remote Access “direct” will never work.

Call your ISP and boldy ask them : “do you perform NAT for multiple customers / CGNAT” or ask them if there exists a (payable probably) option to obtain a Public IPv4 on your own router in stead of a 192.168.x.y “private” IP.

I think the technical support desk of the ISP quickly knows what you are talking about…

17

Some of them are routers (Layer 3) some are Layer 2 only.

Need to know the model.

Ref:

18

The model name is “HL-1GE” you are right it’s the model that u linked.

19

So basically what u said, it means, that I have everything right and the main problem here is my ISP? I contacted my ISP like two months ago, I don’t remember the reason why I was calling them, but I was asking why I have the same IP as others what have Internet from you, and the operator said, that IPv4´s there are very few of them around my village, so if I want my private IP, it will be different from others I can buy it for €4.99 per month + the monthly cost for my internet, so I’m paying about €17.50 + that €4.99 = €22.49 per month. Should I buy it and then it will work?

20

So yes, I think it’s clear the ISP “aggregates” multiple customers behind another NAT.
The paying option for a (probably static - not changing) public IPv4 is to be expected.

With such a paying option I’m about 100% sure you’ll get something working. And remember, you can always activate, pay to try it out/test it and decide yes/no to keep it. Hard to believe the ISP would not be flexible to revert back to the CGNAT-setup.

21

Okay thank you I will do that right now and contact them, to try that and if it will be working I will keep it with that paying option. When I will have any problem with remote access on Plex, will be contacting u here. I really appreciate your time and advices.
