Would requesting a public IP from my ISP allow me to get rid of my Double-NAT problem?

I have spent the better part of this week combing through forums looking for what exactly I need to do here.
So I live in an apartment complex where we are all provided internet via an ethernet port in the wall. I’m assuming these all lead to a central modem / router setup by the ISP or apartment IT. I purchased my own router (Linksys EA6350) so I can control my connection and devices and what not, as most people here do. However, after opening ports, setting DMZ, toying with UPnP, everything the forums recommended, I’ve come to the conclusion that the ISP must not allow port 32400 at their level through to my router. The WAN ip is different than my LAN ip as well (double nat, I believe?).
So what I’m asking is, if I were to call my ISP / complex IT and ask them for a reserved IP or something with the necessary port open, would that let me remote connect to my plex server? I haven’t set my router to bridge mode because I don’t want my devices so unsecured.
Any help is appreciated. Thanks.

Your LAN IP is expected to be different from the WAN IP.

To determine if you have Double NAT, the test is to check the WAN / Internet IP that is displayed on your router internet connection / status page.

Then to compare this WAN IP with the IP you see on the screen when you go to web page http://canyouseeme.org or http://www.whatsmyip.org/

If they differ then you have Double NAT.

Another indication of Double NAT is if your WAN / Internet IP showing on the router is within one of these IP ranges
10.xx.xx.xx
172.16.xx.xx to 172.31.xx.xx
192.168.xx.xx

What you need is for your router to get an internet / WAN IP address that is only given to you and not shared with others and for this IP Address to be in a range that is outside the private IP Range blocks I listed above

Yep, messed up my terms earlier but yeah, my internet IP showing on the router is 172.16.xx.xx.

Cool, now that I have the terms on exactly what to ask for, I will try giving the apartment a call and seeing if they can swing this for me. This seems like something I’ll have to get in touch with them about anyway, no possible way to do it on my end. I’ve read some accounts of ISP’s charging $15-$20 a month for doing this sort of thing in a setup like they have here, but we’ll see what happens.

Greatly appreciate the help, mate.

I have had the double nat for 2+years
And regularly try the newest fixes!

I can get into my isp router but no option to bridge it.
I have had the ISP techs trying to fix - no luck
Get a private IP here is too expensive
I am yet to try bridging my Asus AC88U.
My question is
If I bridge my Asus can it still do all the DHCP serving and all the other cool things (Stats etc)

It is normally better to get the ISP router to be in Bridge Mode and use your own router for DHCP and Port Forwarding etc.
If you do it the other way round - with your router in Bridge Mode, that would be fine provided you have full management admin controls for the ISP router to allow you to configure the DHCP / Port Forwarding

Hi Severin,

I have the option to do portforwarding and turn DHCP on and off in the ISP modem
There are no instructions/manual for the modem and both the ISP and manufacturer will not help. The ISP modem is from Aurora Networks ( A pace company) No model number!
Is there somewhere you can point me to do the pforwarding

There are loads of examples on this web site http://portforward.com to which there is a link from the Plex Troubleshooting Remote Access support page

If your ISP create a NAT for all the clients is impossible for u to connect remotly to your plex. With or without the port forwarding. Please ask to your ISP if u are in a NAT.

Hey N, no I’m not Italian, I just got my name from a Velvet Underground song. I have Time Warner Cable. So I’m going to call them and see if they can assign my specific router a public IP. Thanks!

Yep been there done that. Even bought the portforwarding software with the guarantee they can fix my issue. Nope - they couldn’t help and refunded my money.

I tried yet again yesterday for about 4 hours with multiple forwarding options on both modem/routers - DMZ on both etc etc etc
