Nighthawk(R) X4S R7800 - Can't Open Port 1935

Hi there

I'm having problem with port forwarding on my router.

The port im trying to port forward is port 1935 on my local ip.
I can forward port 10823 used for multiplayer server in farming simulator and it works fine, people can then join my server.

I have the router after my fiber box from my provider, I can't access that (no webinterface, have to call them to make changes). But which is sat to brigde mode by my provider.

 

Im using Nginx RTMP server on my pc, to stream from my mobile (Streamlabs Mobile, Custom RTMP Settings) to my pc. Local it works (localip:1935/live + custom stream key), but when i do it from mobiledata it won't stream (publicIP:1935/live + custom stream key), as it says in all guides.

 

 

Firmware update is: V1.0.2.90

Model: R7800|Nighthawk X4S AC2600 Wifi Router

Hi @FlicherDK, welcome to the community! We'd like to know the following.

 

How are you checking if the ports were successfully forwarded? What results are you getting?

Do you have UPnP enabled?

Has it worked before?

Have you tried any other firmware versions?

How are you checking if the ports were successfully forwarded? What results are you getting? - is there away to test the port? - I only tried the stream the RTMP server that used that port and can't connect

Do you have UPnP enabled? Yes

Has it worked before? - No, but i can open port to a game (Farming Simulator 22)

Have you tried any other firmware versions? With the one when i uptatede when i got the router a year ago.

What you call a "fiber box" looks very much like a gateway. At least, that's what Google suggests.

 

Icotera i6851-00 - Google Search

 

If it has four Ethernet ports on the back that confirms it and you could be in "double NAT" territory, with two routers in your network.

 

@FURRYe38 asked the question because that makes all the difference to how your network operates.

 

You say this thing is in bridge mode and that the ISP has to control it. That's an odd arrangement. Might be worth confirming it with them.

See above.

 

But @FlicherDK reckons to have that covered.

 

I was trying to take it a bit further. Which is why I wondered what we are supposed to make of repeated information.

https://kb.netgear.com/30187/How-to-fix-issues-with-Double-NAT
Couple of options,
1. Configure the modem for transparent bridge or modem only mode. Then use the NG router in router mode. You'll need to contact the ISP for help and information in regards to the modem being bridged correctly.
2. If you can't bridge the modem, disable ALL wifi radios on the modem, configure the modems DMZ/ExposedHost or IP Pass-Through for the IP address the NG router gets from the modem. https://kb.netgear.com/25891/DMZ-on-NETGEAR-routers

3. Or disable all wifi radios on the modem and connect the NG router to the modem, LAN to LAN configure AP mode on the NG router.

It used be be used as a router, but i can't portward it. I have talked with the provider. They said I needed my own router and their router/fiberbox to be in brigdemode as it is now

Re: Nighthawk(R) X4S R7800 - Can't Open Port 1935

One way to tell is look at the R7800s web page on the Advanced tab and Internet section. If you see a ##.##.###.### address for the WAN IP address, the modem is bridged. If you see something like 10, 192 or 172, then this is a private IP address and the modem isn't bridged. 

 

When you set up PF or Triggering rules, be sure uPnP is disabled.
