Hub 5x no DMZ and modem mode

Hi all,

Ive been reading up here an see that the modem mode is not available yet but I see al lot of people going the double NAT route using DMZ.

i decided to try that but noticed I don’t have DMZ option on mine. So I configured it anyway and it seemed to work for a day or two. Now my Unifi Dream machine is dropping connection every couple of minutes. I think it’s DNS but can’t get it working correctly. Anyone having a similar issue and got any advice?

    The usual suggestion is operate Wi-Fi networks in Access Point mode thus avoiding double NAT.

    Rumours are of Hub 5x gaining modem mode in 2024.  Rumours are not roadmaps.

      that will just make things worse

      and where the hell is DMZ this is stupid if it don't have one it should be the other way round DMZ no port forwarding.

        The Wi-Fi AP mode suggested is not an option for me, I have a Unifi setup and don’t have that option. I could deal with double NAT until modem mode became available but with no DMZ option on my hub 5x I’m kind of screwed. 
        surely someone here has the no DMZ option and has a work around??

    Think I would sue VM for not having a DMZ let alone no modem mode 

    I fact let me put it this way if lets say VM are confident in not adding modem mode I would say do you support port forwarding to which they say no to which I say so you might as well remove it and I like to see them try.😈

  • Look I know it’s been talked about for a while and I’m sure the will bring out modem mode but like I’ve asked, is there anyone here that is in a similar situation? No DMZ option and needing to use there own hardware.

  • Yes, me.  I was one of the first customers to get this router that had no modem mode.  I too have expensive Unify kit with several access points cabled into the ceilings throughout the house.  Not to be able to have the external IP through to my unify controller but instead be double NAT is a pain in the backside.

      But you have the DMZ option? I don’t have that option and I’m having a DNS resolving issue I think. Sometimes it works most times it doesn’t 

  • So I have been on the phone with tech support, I’m also based in Ireland but that’s shouldn’t make a difference. I’ve been advised that since we moved from coax to fiber there is no going back. IPv4 is not available on full fiber and modem mode is not available either. I need to get around this issue. 
    ahhhh pulling my hair out!!

      Unfortunately it does.  VM Ireland and VM UK are two separate Companies with different Hub firmware’s etc.  I also believe VM IE use CGNAT IPv6, which again does not exist in VM UK. 

  • Similar situation here. Although, when I signed up I made it clear I needed a router capable of working in Modem Mode, to which the sales rep replied "Sure sir, our router can do that", yet they send me the same crappy Hub 5.

    I contact tech support and now they say "We are really sorry, your router is unable to do Modem Mode". This company is a Joke. It isn't that we are asking for too much, this is just a simple feature, we want to be able to use our own gear, Virgin routers are rubbish.

      So what have you been doing Josel? Does your hub have DMZ?

        your from Ireland that likely why you don't have a DMZ because you have IPv6 

  • Just an update guys. I got a call from Virgin Media and they gave me an IPV4 address. I successfully set the HUB 5x into modem mode and everything is working perfect. Again I am in Ireland but I don’t see why it can’t be done for anyone that requests it

      As a nitpick, I'd like to point out that this isn't happening because you have IPv6, it's happening because you're on their newer platform which uses DS-Lite, and VM deliberately disable modem mode when you're on this platform because some routers don't support DS-Lite.

      The new platform has v6 and the old one doesn't, but that's not the reason you're having this problem.

      I'll also add that the new platform does provide v4 too; however, unlike the old platform, it's CGNATed, which renders a DMZ feature useless since inbound connections on v4 can't reach your router in the first place. There's no point in telling your router to do something with an inbound connection if your router won't ever receive any inbound connections. That'll be why the DMZ feature is disabled.

      When you asked them to "give you a v4 address", they interpreted that as a request to be moved over to their old platform, where router mode isn't disabled.

      I'm mentioning this because I'm super fed up of people blaming v6 for problems that aren't its fault. In fact, all of the problems here ultimately derive from the very problem that v6 is the fix for.

      Would you mind sharing how you set it up? There are few different guides and I don't want to mess up as they already gave me IPv4. just need to setup it so it works with my Omada stuff.

      thx

        "as they already gave me IPv4" Are you in Eire? Because in the UK IPv4 is automatic as IPv6 is not available.

    Interesting you have a hub 5x in modem mode...could I be right about the problem with the hub 5x over here not working... 

  • It does have DMZ I think it’s under wireless definitely not tools. Could be DHCP it’s there somewhere cos I set mine up with TP Link Archer 6e. Speeding slightly faster getting 825mbps on 5x & 880mbps on Archer. 
    reason I can’t give exact location of DMZ is I’m not at home but wanted to tell you it’s definitely there. 
    I think I was advised to use 192.168.0.77 as the gateway. Works fine when I can actually get a signal which has been 10% of the time since install. 
    im trying to get out the contract due to intermittent service. I too was promised the world by salesman. I made it clear I wanted to keep my router etc. I told him install needed to be from rear. I asked him to set DD for 1st of month. Needless to say none of the above happened.

      Hello mfltch55.

      Thanks for your post.

      Sorry to hear about the intermittent service you have been having, the placement of the router and the DD not being set up on your chosen date.

      Would you like me to take a look at these issues and help get then ironed out?

      If so? I will send you a private message to pass security.

      If you can check the logo top right of your screen that would be great. 
      Regards
