Advanced DMZ issue of Giga Hub (HH4000)

stan25zh — Mon, 16 Jan 2023 20:31:41 GMT

Hi,

I was trying to configure the Advanced DMZ on the Giga Hub, and there is an issue which causes the host cannot access Internet even a public IP was assigned.

The problem is the Subnet mask returned from the Giga Hub. the value of Subnet mask acquired by the host is 128.0.0.0, which definitely is not a good subnet mask. If I kept static values of IP (the one auto-acquired) and DNS servers, and use Subnet mask as 255.255.255.255, the Internet access is all good. But this is just a workaround since the public IP might change with new connections.

Could you fix this bad Subnet mask issue to make the Advanced DMZ really usable?

Thanks!

Hi @ZaneP

Thanks for providing the information.

The solution discussed in the first link, is not really about "Advanced" DMZ. The ADMZ assigns the public IP modem acquired during the connection to the device (which been put into DMZ) directly, instead of assign an Internal "192,168.2.x" IP using DHCP.

The second link is relevant. It mentioned the issue I'm facing, the wrong Subnet mask assigned. But the solution is about to get it fixed in the device instead of having it fixed in the HH4000. I am still hoping it can be fixed by Bell with a firmware update. @User59

There is no real solution in the third link.

I will see if I can get some help on the DSLR Bell forum you mentioned.

Thanks again for the help,

Stan

Hi @stan25zh ,

Hope you make some progress in resolving this. The DSLR Bell forum should be a good resource for you.

Just a small nitpick: The Giga Hub and the Home Hub 4000 are not the same modems. You need the Giga's most recent firmware, which I think is now at version 1.15.1.

This update has not been deployed to all Bell users with this modem. You need to send a PM to Bell Forum Moderator @BellPatricia requesting it be pushed out to your modem.

Cheers,

Hi @ZaneP ,

I think Giga Hub is the alias of Home Hub 4000, based on this page, https://support.bell.ca/internet/products/home-hub-4000-modem.

@BellPatriciahas already helped to push the firmware 1.15.2 to my Giga Hub, that solved the PPPoE passthrough issue, and which is the way I am using to make connection from my own router. I am just thinking if @User59 can fix the Advanced DMZ issue, then customers may have more choice here. 🙂

Anyway, I probably gonna try DSLR Bell forum.

Thanks again!

Stan

As of today. September 9. I still having this same issue. I have my own firewall, it is called "Firewalla Gold Plus" you can google it. It is a 2.5Gbps firewall and I have 3.0Gbps Bell service. I am currently using PPPoE bypass, everything worked fine but my speed is cut to around 1.3 Gbps Down. I guess my Firewall isn't fast enough using PPPoE. The only way I get any close to 2.5Gbps is to use Advance DMZ on Bell Modem and then use DHCP on my Firewalla. Yes I get about 2.3Gbps down when I using this way, but the problem is I getting Network Latency issue! If I ping any sites... 1 out of every 5 times I get a time out! When is Bell going to fix this??? I google around, and it seem this issue been around for a long time! Bell just ignore it! I am just waiting for Rogers to have Fiber to home and I going to move ON! This is crazy! Either you give us a "Bridge Mode" or fix this! Pleases!!! I am getting half the speed I paying for!

Hi @cclo

Just a few questions:

Are you running the speedtest directly from the Bell modem's dashboard? If yes, what are the results?
Make sure the 10Gb port on the modem is set to 10Gb (not "Auto")
Are there any known issues when running Firewalla and the PPPoE protocol?
Are there any known limitations for Firewalla and 3Gbps (and higher) transfer rates?
Could the speed issue ("I guess my Firewall isn't.....") possibly be a Firewalla CPU cores problem?
ADMZ is known to add latency(?) https://forum.bell.ca/t5/Internet/Packet-loss-and-increasingly-high-latency-at-fixed-intervals/td-p/13259

#1, above: it's important to measure the inbound connection from Bell to the gateway modem. Need to be be sure that you're getting the speed you're paying for.

Unfortunately there is no indication that Bell will configure its Sagemcom/Hub modems to run in pure bridge mode.

Maybe some other Firewalla users who follow these Community forums will add their ideas to this thread.

Cheers

Okay... I going to show you right here... My limitation of Firewalla is 2.5G. It is running Intel J4125 Quad Core CPU and 4GB on board.

If I running PPPoE Bypass. which mean I using Firewalla PPPoE with my Bell Password to log in... I got about 1.3Gbps.. See below

Then I try to use Bell Advance DMZ, See below, because the HH4000 only have "1" 10Gbit Port, I have to put my Firewalla at the first port on the HH4000, and I got an IP address of: 169.1.1.1. And using DHCP on my Firewalla. My Speed is improve to more the 2Gbps... testing on the same Bell North York site. But I got tons of latency issue by Firewalla.

Hi @cclo

You're not understanding what I mean about the speed test. You must do the Bell-server-to-modem speed test that's on the Hub's dashboard.

Log into the Hub. Click on Speed Test.

Then click on Start Test

Then you'll see the results.

I have a 1.5Gb/940Mb plan, but as you see my d/l and u/l is a little overprovisioned by Bell, so my results are even better.

By doing this test first, it will confirm that your modem is getting the speeds you pay for. Then you can other speed tests from another device. Bell will not help on d/l and u/l speeds past their modem to your Firewalla. Their support ends at their equipment, not CPE.

In my opinion don't try to use ADMZ. Connect the Firewalla to the 10Gb port on the modem and connect with PPPoE.

Hope this helps.

I have the same issue when I try to use Advanced DMZ. I think the reason is because we are using the 10Gbp Port. If you use any of those Yellow Ports... you will get an IP address... and you will see your IP address even on Advanced DMZ... But those ports are only 1G.

Re: Advanced DMZ issue of Giga Hub (HH4000)

cclo — Sat, 09 Sep 2023 23:15:17 GMT

I understand... The speed test under the Modem is fine of course, I getting 3.0Gbps. But there are people out there that wanted to use there own FireWall. The reason I using it, because I have IP cameras and a server at home! For me to access my server and my IP Camera from outside, I need to VPN to my home's network. In order to do this, I have to set up my own firewall... The problem is Bell doesn't have "BRIDGE MODE" like Rogers. If you ask them, there solution is "Advance DMZ". And IT DOES NOT WORK! "I AM" using Firewalla to the 10Gb port and log in using PPPoE, and by doing so... My 3.0Gbps Connection became 1.3bps... As I show you on the speed test on the last post. I also show you the same test under Advance DMZ and DHCP and the speed double!!! I don't understand why Bell still using PPPoE in the first place... As Rogers and everyone else use DHCP. PPPoE was use back in dial up days for god sake!

I have always understood that your LAN maximum speed is not the same as your WAN subscribed rate. But you have only now confirmed that Bell is delivering the speed you pay for.

It's a situation which frustrates you, but one for which there is no fix without unwanted outcomes (latency problems; degraded transfer rates). Don't be upset with me. I'm trying to get you to accept reality.

I would love to run my own Asus router in bridge mode to the HomeHub 4000, BUT I CAN'T! Keep in mind that 99% of Bell's retail customers don't have the requirements that you do. If you require a true bridge mode, then you won't get it from Bell.

Bell's gateway modems HH4000 and GigaHub have an ONT that's soldered onto the board. It can't be removed and plugged into your router. So there's no bypass possible.

There are no other workarounds, so you'll have to deal with it. Sorry.

cclo — Sun, 10 Sep 2023 00:15:15 GMT

Hey no worry, I not upset with you.. I didn't get into this issue until my speed went above 1 Gbps. When I first join Bell, they given me a HH3000 and I never have issue with it. Once it above 1.5 Gbps is when I started to have issue. Right now Bell is the only one that have Fiber to Home in my area. Rogers kept talking and talking but never have any action! When I was with Rogers with there DOCIS modem, I have to reboot that stupid modem once every few weeks... and with Rogers I will never get the upload speed I am getting from Bell... I love Fiber to my house.... I just hope Rogers can get there act together... The worst case is Rogers kept call me!!! I told them, don't call me until you have Fiber install to my house. Again, thanks for the help...

I recently got HH4000/Giga Hub and connect to my pfsense. I was able to see public ip when I set pfsense to Advanced DMZ. I recently unplug DAC/Media converter to plug to ups. Then I notice that I'm getting 192.168.2.x instead of public ip. I checked that pfsense is in the DMZ and advacned DMZ is checked. I try rebooting the pfsense and still using 192.168.2.x as the gateway instead 142.198.241.x. This causing double NAT issues prevent from access device from the internet.

ZaneP — Sun, 10 Sep 2023 17:28:50 GMT

Did you reboot the modem?

Re: Advanced DMZ issue of Giga Hub (HH4000)

NeVaR — Sun, 10 Sep 2023 21:05:39 GMT

I plugged for 10 sec. and i also reboot my pfsense but no luck. pfsense still showing 192.168.2.x rather than 142.198.241.x. Unless there is order of step that it need follow in order to get the public address? I only solution that I can think of is to do port forwarding to my pfsense. So far I can access application remotely. My GigaHub is running firmware 1.16.5 and hardwrae version 5690-000001-000

I'm having same the problem, in ADMZ the interface of my firewall receive an IP with a mask of /1. This is stupid as it includes half of the possible IP v4 of the world!! I understand Bell is trying to include the default gateway ( 10.11.23.105 in my case ) pointing to the same interface but it's just lazy engineering. All of the other interface on the firewall are conflicting because the network includes the RFC1918 class A IP 10.0.0.0/8.

Bell - Please fix the ADMZ so it provides proper subnet mask according to proper networking instead of doing lazy engineering corner cutting techniques.

Benze — Sun, 08 Oct 2023 04:24:54 GMT

@TECHEVO Have you found a solution to this? I just noticed that I got a subnet of 128.0.0.1 to my DHCP request on the ADMZ as well. And am not sure what the correct fix is to this problem.

I'm running a UDM Pro connected to the ADMZ port, and while I can ping and curl from the UDM Pro ssh, none of my devices on the network are able to route to the internet. I'm not sure if this is related, but am becoming quite frustrated with the ADMZ configuration.
