Simple Port Forwarding Hub 5 Not Working

Hi everyone,

I have been doing a simple Port Forwarding task with the Hub 5. I have done this before with previous Hubs countless times and not had any issues, but can not work out what has gone wrong this time. I have a simple set up of just a desktop PC and the Hub 5, no Raspberry Pis or additional router/modems involved at all. This is all just so I can host a video game server. 

Is there something I am missing, or is this an issue with the Hub 5? I have seen multiple posts about how Port Forwarding seems temperamental at best with the Hub 5 and many have had to downgrade back to Hub 3/4 to get that functionality back. 

Things tried/checked so far.

  • Double checking all Port Forwarding related rules. No Duplicates, correct public and private IP address, etc
  • Checked any firewalls that may cause issues in Windows or the Hub itself. Added rules in that allow access through those ports and tried an attempt with the firewalls deactivated.
  • Tried it with a different desktop entirely (changing the private IP etc to match the new device etc)
  • Contacting VM support who don't seem to understand the issue but also don't seem to want to elevate it. Only feedback I am getting is to reset the router, which I have gone along with to no avail.
  • Checked the game server itself is working and can be connected to via the local network
  • Checked numerous different website port checkers, none of which can connect.
  • Tried it with and without UPnP, DMZ and DHCP enabled.
  • Plenty of restarts of all the devices involved and the Hub itself.

I am not really sure where to go next outside of requesting an older Hub or buying more equipment myself, which is obviously something I would rather not do. I have done this enough times with previous Hubs and not had any issues outside of the odd stupid mistake where I didn't notice my Private IP for the device changed etc, so I think I have covered all my bases and not made a mistake on my end.

    VM would like you not to Port Forward on their safe router mode so you should use modem mode

      Is this confirmed? Does this mean that the Hub 5 is straight up not fit for purpose if you want to port forward and have wifi without needing to buy additional hardware? 

      This seems like a strange design choice when the previous Hubs were able to do this fine.

        Is this the process or is some other approach involved ?

        1) Add the machine's MAC and IP to the DHCP Reserved list

        2) Add the Port Forward rule

    ^So you check it works in modem mode but might not work in router mode and you don't support 3rd party equipment even a PC.

    Heres your internet connection upto the hub but we don't guarantee anything will work after that is what your saying.

    Did anyone get a response, or any advice indicating how to make port forwarding work?  I have a simple Hub 5 wire-connected to a network of several machines, and I want to run one as a static-page web server. I have tried specifing that machine's address as static, adding a port-forwarding rule on port 80. and running a simple test web server utility on that machine - and I cannot connect to it, no matter what I try. 

    Has anyone else got a web server running using hub 5 and port forwarding, and if so, can they tell us how they did it?  Or perhaps virgin staff could write a simple set of instructions...

      You said the HUB 5 is in modem mode?

      If it is there are no options to port forward, it's controlled on your router, as I mentioned above.

    This is clearly a software fault with the Hub 5s software. I switched from BT where I had one static NAT rule and some automatically provisioned ones using UPnP. Everything worked fine on the BT Hub, but although I can create a static NAT rule, and can see the ones automatically provisioned using UPnP(UDP hole punching), no NAT is taking place.

    @VirginMedia, this is not an unusual requirement and is clearly a software issue on your Hub 5, not a feature constraint, it's incumbent on you to issue a fix for this. I'm checking to see if this lack of basic functionality invalidates the contract I have with Virgin Media.

    I have just had VM replace my Hub3 with a Hub5. I have reapplied my port forwarding settings and it all seems to be working fine. I got to this thread because it seemed not to be working at first, but that turned out to be because my Dynamic DNS had failed.

    FYI, in case it helps:

    • Hub is in router mode
    • uPnP disabled
    • DHCP disabled
    • Hardware version: 1.2
    • Software version: LG-RDK_6.9.35-2302.6

    @jeffas I am experiencing the same problems as everybody else at present. To my knowledge, it is a Hub5 device that I have here, but the software version is entirely different to what you are reporting there. Does your Admin -> Info page look anything like this?

    It appears from this that the router has no public IPv4 interface, though I am being given a specific IPv4 address consistently from any 'What is my IP' sites that I visit. Is that an IP address of some other node within the VM network though perhaps?

    I have set up a couple of port forwarding rules to forward traffic to the Asus ZenWifi router I have behind the VM router (and for the Asus router to forward that onto the applicable servers behind it. If I connect to the VM Wifi, I confirm the forwarding rules on the Asus router allow traffic in, but any attempt to get to them from the public internet using the IPv4 address I found is not working. I have also tried connecting to the router's IPv6 address via a browser (eg. https://[ipv6address]:12345) but it times out.

    Last of all, I'll be knackered if I can find any option in the router configuration to switch to modem mode. Does anybody know where I can find that? Although I would prefer to keep the VM router in router mode, I don't need its Wifi, so could switch to modem mode if it allowed the incoming traffic properly.

      Hi rixybix 

      You need to repost your photo with the MAC address blanked out/removed before it can be approved.

      Looking at your picture and the software version (3.7.4-23065) it appears that you have an XGS-PON connection and therefore you don't have a hub 5, you have a hub 5x

      EDIT - Looking at the DS-LITE-FQDN you are based in Ireland - these forums are for Virgin Media UK domestic customers so the help you can receive will be limited.

    rixybix  If you are with VM IE I believe you need to ask to have IPv4 only.  If you have IPv4 and IPv6 your IPv4 address is CGNAT and will not work with Port Forwarding?

    As VM IE and VM UK are all under Liberty Global, CGNAT is something perhaps the UK gamers can look forward to ……

      @Adduxi and @newapollo, thank you both for your help there. You are absolutely right, I am in Ireland. 

      Having explored this a little more over the weekend, I am debating whether to ask for IPv4 only or to try to make things work with IPv6 alone. Despite having done a training course in IPv6 many years ago, my knowledge of it has all leaked out, much thanks to general industry lethargy towards migrating to it over the years. Perhaps now is finally the time! 

      My main reason for wanting port forwarding is for my son to host a Minecraft server. As I understand it, Minecraft itself supports IPv6, but I believe ALL parties wanting to connect to it will need to be properly set up with IPv6 also, and I don't know how well supported it is at the moment!

        There is a lot of IPv6 support from big ISP’s but I’ve no experience of setting up. It will limit the user base for sure, eg VM UK for one as they don’t have IPv6 at all.
