Unable to enable DMZ on FAST5364 3 firmware SG4K100136

mouetteboat — Sun, 15 May 2022 20:26:31 GMT

Hi,

My sons xbox has stopped working in the past few weeks. I'm getting a NAT Type error, I've tried a number of recomended fixes from the forums without any luck. Next option is to use the DMZ setting on the router but whenever I enable it, and apply the changes its not keeping them. If I go back in to the screen the settings have been lost.

Any suggestions?

Thanks

I will not use the DMZ due to losing the protection of the router's firewall & would always recommend port forwarding instead. Which TCP or UDP ports would need to be forwarded if you went for this solution? However, in the meantime, I will ask the TalkTalk Products Team to test this for you.

Hi mouetteboat

Can I just check, have you tried factory resetting the router using the pin hole reset for ten seconds?

Thanks

Debbie

I would prefer not to use the DMZ but I'm running out of options.

Thanks for the replies. I'd prefer not to do a factory reset as I don't want to reconfigure the router afterwards.

If I enable the "Low" setting on the firewall everything works fine. As soon as I change the setting to "High" it stops working. I have tried enabling uPnP, when I do so I can see the rule for the Teredo UDP being added dynamically to the rules but the xbox still doesn't work.

I have tried adding the required ports manully to the firewall (see attached) but it still fails to connect (also added all the standard ports for https http etc etc etc).

You do not add ports to the firewall, this is done in the port forwarding configuration. Which TCP or UDP ports do you need to forward & I will try and help you.

These are the ports I need to open

These ports must be open to connect to the Xbox network:

Port 88 (UDP)
Port 3074 (UDP and TCP)
Port 53 (UDP and TCP)
Port 80 (TCP)
Port 500 (UDP)
Port 3544 (UDP)
Port 4500 (UDP)

I have done a few examples for you:-

Thanks for that I have added the ports to the port forwarding config, but the problem persists. I 've attached a screenshot of the rules.

KeithFrench — Tue, 17 May 2022 20:55:51 GMT

Your screenshot has cut off the internal ports & so is a bit meaningless. Please can you try again?

Here you go.

Thanks for that, there is nothing wrong with the port forwarding so the problems point towards the XBox. Is this an actual console or the XBox app in Windows?

Re: Unable to enable DMZ on FAST5364 3 firmware SG4K100136

mouetteboat — Wed, 18 May 2022 11:43:05 GMT

It's an actual console. On the router I have DHCP static reservation configured for the xbox

KeithFrench — Wed, 18 May 2022 12:15:45 GMT

The fact that you have a DHCP reserved IP address set up for the XBox, there shouldn't be any issues there. However, please can you get me a screenshot from the XBox of its networking configuration. What happens when you check some of the TCP ports with the XBox running? From a browser on any locally connected device, go to:-

https://portchecker.co/

Do they report as open or closed? The UDP ones will always report as closed as these port checking sites are not compatible with UDP.

If the TCP ones are closed, then is the XBox actually opening these ports, which is its responsibility to do so. These ports exist purely on the XBox, the router's port forwarding merely provides a route for them from the internet to the XBox's IP address. If they are closed, then you will have to contact the XBox support people.

Thanks.

From the website you provided they are appearing as closed for the 2 TCP ports. I installed a port listener on my PC for the same ports, updated the IP in the port forwarding config on the router and they worked, so it does look like an xbox issue.

Thanks again for all your help.

On second thoughts I'm not convinced it is the xbox. If I switch the firewall off it works...any more ideas?

Hi mouetteboat

The default security setting for the Hub firewall is Medium. The 136 update appears to have reset security to High. Have you reset to Medium, saved and rebooted the Hub and retried?

Re: Unable to enable DMZ on FAST5364 3 firmware SG4K100136

KeithFrench — Fri, 20 May 2022 08:47:35 GMT

@Gondola may have a point, my firewall is still on Medium, which I have never touched. When it got upgraded I would expect the router to keep its existing settings, so if you have done a factory default, that might have changed the firewall setting.

Hi @mouetteboat

I have just done a factory default on mine & the firewall remained on medium, so the firmware is not the issue here. However, if you have your firewall set to high anyway, then this might cause the issue. Please can you confirm your current firewall setting & please can you also confirm the hardware revision of the router?

@Gondola if yours defaults to high as you have said, which hardware revision are you on?

KeithFrench — Fri, 20 May 2022 09:36:35 GMT

Hi @mouetteboat @Gondola

I have just proved that setting the firewall setting to High, does not stop port forwarding from working.

mouetteboat — Fri, 20 May 2022 21:50:55 GMT

I've set the firewall to medium and it's now working
