"Strict .NAT", open and forward ports
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
Hello,
there I got this modem yesterday.
When I am opening the game I play, it always gives me the note, that my settings are on "Strict .NAT",
so I will need to open and forward some specific ports.
I remember having done it on another router, but here it kinda seems a bit over-complicated?
I have port triggering, but not port forwarding f.e.?
Under port triggering, it only shows 9 applications to select, not the one i play, and some I don´t even have installed?
These are the settings I will have to change in order to be able to properly use the modem.
If it´s not possible I have no reason to keep the modem tho... on my phone hotspot I can use an app for it....
Ports that should be open:
| Platform | TCP Destination Ports | UDP Destination Ports |
| PC | 80, 443, 1119-1120, 3074, 3724, 4000, 6112-6114 7500-7509 30000-30009 |
80, 443, 1119-1120, 3074, 3097-3196, 3724, 4000, 6112-6114, 27015-27200 |
Ports to forward:
| Platform | TCP Destination Ports | UDP Destination Ports |
| PC | N/A | 3074, 3097 |
Additional question/note:
Do I have to restart the modem each time I change something in the settings?
- If I use UPnP it doesn´t change the error I get notified in-game.
- Also I turned off following ALGs:
L2TP
IPsec pass-through
H323 ALG
SIP ALG
- turning on DMZ with my computer´s IP doesn´t change it either.
Hi, are you trying to play computer game or play via xbox or play station?
Regarding the port forwarding or to open ports, please don't use port triggering, but use Virtual Servers under NAT Forwarding.
If it still doesn't solve the gaming issue, please check Internet IPv4 address of Status page on the web interface to see if it is a public IP or private IP.
If it is a private IP address, it means the ISP uses CGNAT on their end, that is to say, there is another NAT in the front(ISP side) which causes the issue, please try to contact your ISP to see if they could assign you a public IP address directly.
Is this correct according to the ports written more above?
Because TCP destination is N/A, I switched to UDP. HTTP was also said to be most efficient so I used that.
Edit: Ports to be open = internal
And ports to be forward = external i guess?
So I switched those two
---->
I have to use the ip from the Mifi device?
Yes, these ports more above were provided by the game developer. I can not post links in here. But if you search for "help dot bungie dot net" and then search for NAT, it will come up at the top.
So I have to open each one of those ports? Because from what I remember, opening one was enough before.
But I am no specialists as you notice.
Besides 80 I tried the others as well. But not multiple ones at the same time.
Can you show me in a screenshot how to correctly open those ports?
