No Internet connectivity when using Advanced DMZ

brandon1 — Tue, 23 Jul 2024 16:29:05 GMT

This morning I noticed that my UDM Pro showed a no internet connectivity and my WAN IP being my external IP. After restarting my Bell modem, toggling advanced DMZ, and restarting my UDM Pro, I still had no internet connectivity (and my WAN IP being my external IP). Should I turn off Advance DMZ and allow my UDM Pro to get an internal IP, I am able to connect to the internet.

Did something change on the Bell side? Why would I get no internet connectivity using Advance DMZ?

If your WAN IP is your external IP, you should have connectivity.

Do a tracert, see where the path stops just to get an idea of where the issue might be. Also check your UDM as they tend to push updates from time to time.

Agreed but I don't have connectivity when my WAN IP is my external IP unfortunately.

Try removing the UDM and try directly at the LAN port of the home hub. If that works, then it's not a ADMZ or modem issue but a LAN network issue.

I’ve tried using Advanced DMZ directly with my Windows laptop. The laptop gets my external IP but no internet connection.

That is odd. Could be a bug in the firmware but just to be clear: you are not trying to establish a PPPOE connection, just using ADMZ correct?

You can also look here to see what your subnet mask is. It's possible they pushed new firmware to the HH with a bug regression.

Correct. I am just attempting to use Advance DMZ, not PPPOE. Its odd because it was working fine up until a couple days ago. I looked at the modem logs but didnt see anything that stood out.

Try to see what your subnet mask is. Maybe that bug snuck back in the firmware.

What should it be?

Re: No Internet connectivity when using Advanced DMZ

Vanadiel — Thu, 25 Jul 2024 21:08:08 GMT

255.255.255.0 is the one normally used.

Is someone at Bell able to check on their side to see if anything is wrong?

I use an UDM Pro SE and it works fine for me, but I do establish a direct PPPOE connection rather than ADMZ.

Sometimes the order on how to boot things up matters. Try rebooting the modem by itself, or the UDM by itself to see if that reestablishes connection.

Yeah, I’ve tried multiple resets.

I have even with as far as factory resetting both the modem and udm pro

Hey there @brandon1. Thanks for reaching out in the Bell Community 🙂

Great troubleshooting suggestions from @Vanadiel. I just wanted to jump in here too and see if you can try disabling/re-enabling ADMZ after you've rebooted.

Please keep the Community updated.

Hey @BellPatricia. I have rebooted and disabled/enabled ADMZ. No change.

This is a long shot as you are not using a direct PPPOE connection, but try setting VLAN 35 on the WAN interface of the UDM.

I don't think that is the issue, but you never know. You can also check the system log of the UDM to see if anything is logged related to your WAN IP/Connection. It's odd you get an IP but no network connectivity.

I would say its not the UDM though, seeing as ADMZ does not work with a Windows laptop connected directly to the Gigahub.

Vanadiel — Fri, 26 Jul 2024 17:44:24 GMT

Does it work without ADMZ?

Yes, both the UDM and Windows laptop work when ADMZ is disabled.
