Hi all,
Wondered if you could help me at all.
I have a ZyXEL USG40 and Sky Fibre Pro as my ISP. The problem I have is that I'm currently using the Sky hub (modem/router) to connect to the internet as they don't allow you to use your own hardware. So, currently, my USG is connected to the DMZ of the Sky hub (SR102).
This works, but is really annoying as I cannot get a true WAN-IP into my USG device. So my WAN-IP is always simply the IP of the DMZ port (192.168.1.254).
Is there a way I can somehow get around this issue? On the old Sky hubs, you could set it to "Router Mode" and this would act as a modem-only setup. However, Sky do not allow this configuration with the SR102 hub.
Any thoughts on this? I'm happy to either ditch the SR102 and move back to a BT Openreach modem with the USG connected directly to it, but my understanding is that this requires a very specific setup (I have already extracted my username and password from the SR102, which is hard-coded into it)... but apparently, you need to be able to pass this over via a "DHCP Client ID" (option 61) and support MER format.
Has anybody done this before with the ZyXEL USG series? Or does anybody know a simple way, perhaps via routing or virtual interface, to get the TRUE WAN IP into the USG device?
Any help would be VERY welcome as this has been driving me nuts for months. I have attached an example of how my network is laid out (IP's are just for demo purposes), to help you to see the problem.
Thanks in advance
