Hi - Got a mini server that I want to sit on a DMZ. I have given it a static IP address, but that seems to remove it from the list of devices I can no allocate to the DMZ. The help text clearly states that the DMZ supports a single static IP addressed device. I have tried to both select the device and enter its IP directly. Both fail when I go to save the config as it states that it is an invalid device selected for the DMZ. Very frustrating. Hope someone out there has a solution.

Hi - I've learnt a bit more having discuss the issue with a colleague who also has this setup.
If you have a business service with a single static IP assigned to the hub, you can use the DHCP table settings to allocate a fixed IP to the device you want in the DMZ, then assigne the DMZ and it all works. Effectively the hub has a single PPPoE connection and is allocated a single IP address that comes from a static pool rather than the normally dynamic pool. What I have is a business service where I have purchased 5 additional static addresses. You enable this on the hub using the static IP config, giving the hub another address that is different to the dynamically assigned address that is still used and given to the hub for routing all devices that are not using the static IP service. Now if you take one of these separately purchased static IP's and assign it to a device (my server) the DMZ option is no longer available. This is very annoying and clearly a feature/failure of the software. Feature Request please Mr. BT. Allow DMZ to work with your static IP addresses. BTW the main reason I need this is because the server I'm using gets a large number (over 10K) of inbound TCP and UDP connections. The BT hub cannot cope with this and drops reachability to external sites that my internal systems montor to prove connectivity through the hub. I think that if BT cannot add this function, I'm going to be looking elsewhere for a VDSL2 modem/router.
Sorry - yes I am, I got to this via the Business portal. IT is a truely painful process. Can you tell me where the business forum is?
