NAT Type still strict after port forwarding

I'm having trouble opening my NAT type even after forwarding ports. I followed the guide on PortForwarding.com and nothing changed.

-TP-Link TL-WDR3500 router (followed the TL-WDR4300 guide, but it should be the same)

-Xbox one has a static IP address

-Forwarded the following ports: 53, 80, 88, 500, 3074, 3544, 4500

-DMZ host is enabled for XBox IP

After testing multiplayer connection and checking my detailed network statistics, my detailed NAT information says "Your network is behind a port-symmetric NAT." Not really sure what to do next. Any help will be appreciated. Thanks.

Nat type Strict after port forwarding.

@VexX Diegoo hey hey

Can You try to do factory reset on Your gateway and after that set only UPnP to enabled state. without DMZ or port forwarding. After that we will try other steps.

 

Nat type Strict after port forwarding.

Fritzbox on the fritz...not the first one . you might try a factory reset to "undo" everything and also "clear alt mac address " on xbox one...... if I remember right , the last guy found a check box in the settings about "teredo tunneling " and or "iv6p
disable" ....

 

What kind of modem and who's your isp ?.....DMZ and port forwarding are not doable together (or not needed).....all you should need is UPNP enabled ....

oh , wired or wireless ?

 

No modem, I just plug an Ethernet cord directly into my router (I live in an apartment building). My ISP is Access Media 3. And I'm using the WiFi to connect to my Xbox one.

 

you could try it wired just to see but the problem is probably at the modem and whoever controls that ...

 

Have you tried clearing your MAC address. 1) Settings 2)Network 3) Network settings 4) Advanced Settings 5) Alternate MAC address 6)Clear. Your system should restart on its own after this but if it doesn't go ahead and do a hard reset.
