New range of static IP addresses not working after upgrade

[andyt22]

My BT Infinity connection was upgraded this morning from 5 static IP addresses to 13 along with a speed increase to 80/20 which meant a new block of IP addresses. I received a text at 8:17am to say the upgrade had been done and although the connection is working, the static IP address feature isn't even though the BTHub3's login page says static addresses are enabled.

I have powered off the VDSL modem and the BT hub for at least 2 minutes several times since 9am as instructed but the new static addresses don't seem to be available. Do I have to wait a few hours for these to become active? Interestingly. I noticed the old static addresses were still usable for about an hour after I first powercycled the modem/hub but they are not now.

Hi Andyt22,

If you have upgarded from a block of 5 IP's to a block of 13, you will need to manually reconfigure your router, to use the new range as they are not auto assigned to the line.

Is there any documentation available on manually reconfiguring the router (BT Hub3)?

If I go to Advanced Settings > Settings > Static IP and then click on 'Configure' at the bottom right hand corner, I get a page relating to one of my servers and in the section called 'Addressing' about halfway down the page, the 'Use public fixed IP address: yes/no' and 'Always use this IP address: yes/no' buttons are greyed out and already set to 'no' and can't be changed.

In the section Broadband > Routing, the static IP addresses are all in the routing table with subnet mask 255.255.255.255 and gateway 0.0.0.0 and apparently rourined to interface br0. Is this correct? Dynamic routing and briding are both set to 'no'.

Hi andyt22

If you go to Hub 3 Static IP Addressing, this is a guide on how to configure the router to use your static IP range.

Thanks for the info. I just couldn't get the drop down box shown in the online documentation where you can select which static IP address to use to appear and in the end I reset the hub to factory defaults and started again. This time the IP selection box appeared and I was able to configure static IP addresses but I now have a new problem - even with the firewall disabled and port forwards for web and ssh configured, the servers with public IP addresses cannot access the outside world (although they can ping the BT router gateway address) and the servers cannot be accessed from outside (not even pinged even though I have the 'allow incoming ping requests to static IP addresses' enabled.

Maybe I'll leave things to the morning - I remember the static addresses didn't work at first when the Infinity connection was first installed a year ago but started working a day or so later.

Got up at 5 this morning and found all static IPs were working. I guess routing needs to be configured on the BT network upstream of me for this to work but it's all working fine now.

One quirk of the BT Hub3 is that if you have an internal server with a statically configured IP address (so that it doesn't issue any DHCP requests), the hub detects it but in the Static IP configuration page you are not offered any choice of external static IP addresses to assign to it and the yes/no buttons are greyed out. After reconfiguring the server to use DHCP, the BT hub responds and gives it an internal LAN address and then the IP address choices box appears.so you can reconfigure the DHCP server to assign an external static address instead.

Then you can, if you wish, reconfigure the server with the same fixed static address. Afterwards, the BT hub's static IP page changes from 'DHCP' to 'static', the address choice box disappears and is replaced with the external static IP address you are using on the server and the yes/no buttons are greyed out.
