Hi,

So there is still no bridge mode available for Connect Box Fiber 3. I tried the DMZ option but it’s completly not forwarding the traffic to IP set. Only port forwarding works for me.

Any information on updates to the modem so DMZ works or maybe making bridge mode available for the connect box fiber 3?

Thanks
Jed

yesoos A bridge mode is not available for fiber modems. In the medium term, there will also be no bridge mode for fiber modems.

The DMZ mode is actually there to connect your own router, via which you then connect and configure all your devices. The firewall is deactivated for the internal IP in DMZ mode.

Yes but I thought DMZ mode will actually also forward all of the ports to that given IP. But seems it does not do that completely.

With DMZ set to point on my own router I still have to configure port forwarding on the modem. I thought with DMZ that should be all forwarded to my router.

yesoos What happens if you open some ports on your router, which is in DMZ mode, and then use a port checker to see if the ports are open?

@Daniele_Sunrise - seems that DMZ mode does not function properly - If I do DMZ only and try to connect to a port that is open on my router - port does not work at all.

Once I add that port additionally to port forwarding - then it works. So it seems to me DMZ mode is broken or does not function properly.

Thanks

yesoos Our modem team has a question for you. Which ports exactly are you redirecting and are not working? We would like to reproduce this as accurately as possible and would appreciate your help.

@Daniele_Sunrise I’m trying with port 51820 UDP (Wireguard) - when I set only DMZ and point to my router - I’m not able to connect. I’m able to connect after adding port forwarding additionaly on the modem.

yesoos Same here and I am wondering why. I am sorry for jumping into your post. I also want to know same.

yesoos

@Daniele_Sunrise as you can see more people have the same issue. Any information from the modem team?

Daniele_Sunrise

yesoos No, we have not received any feedback from the modem team. The analysis will continue. May I ask you to contact our support team on 0800 707 707 to open a ticket?

Hi there,

Is there any further update on this? I’ve seen similar behaviour when testing the DMZ functionality with simple TCP/UDP ports where port forwarding rules are required. By themselves the port fowarding rules are too limiting for the full functionality need (i.e. additional protocol support) so I was hoping that the DMZ option would provide a suitable alternative. Thanks.

DMZ on Fiber 3 is a hoax and not working. There is no difference in whether or not it’s activated and you have to add your ports for forwarding manually. @Daniele_Sunrise Would be good if you can check again with the modem team. Ports I am using are 5000 and 8123.

@Daniele_Sunrise Your team has been analyzing for 6 months and there is no answer? If the CB3 doesn’t support bridge mode, at least the DMZ feature should be a reliable alternative…

Daniele_Sunrise

Latzo Yes, unfortunately there is no news about this yet and the bridge mode is still not possible for fiber modem.

Same issue. DMZ does not open any ports. Connected to a Router and forwarded ports there.

Thanks for a solution.

hello ramsambam

Did you try to factory reset the Connect Box 3 FIBRE before setting up DMZ?

You can add me to your party… I can confirm that, as of today, the problem persists.

My fiber connection got activated today and I sadly discovered that I need to manually forward ports for services to become visible from the outside.

The DMZ seems to do nothing.

Hi there

I am on the same boat.

And no news until now !

Moreover I am unable to open port 51820 (Wireguard) and ports 5000-5001.

Port checker respond closed after port forwarding settings.

A solution would be welcome.
