Orcon Genius NF4V bridge mode with a real firewall?

Anyone using the Genius White with their own firewall?I'm due to renew my orcon contract next month and I'm considering moving from POTS to Genius, especially if I can get VDSL (sadly fibre isn't an option).Key requirements

Run my own firewall

Netgear R7000 using dd-wrt tomato

Able to support existing phone jacks in house

Work with alarm without an expensive upgrade

Now for (1) I need to be able to run the modem in some sort of a bridge mode so it doesn't manage the firewall. Anyone got a good guide on this or done it recently? I've noticed an old GZ guide but it doesn't mention if the ATA ports keep working

For (2) my modem will be no where near where we keep our answer phone + wireless phone base station. Has anyone tried wiring the ATA port off the Genius back into the house phone wiring?Also if I can use the existing in wall cabling I can probably keep using my existing alarm setup (3).I know where the master splitter is and if I can switch to VDSL I probably want the modem as close as possible to the splitter which is in the garage. Anyone else have the modem in the garage but the rest of their wiring elsewhere in a house without good structured cabling?I'd love to re-cable the house properly, but that is atleast 6-12 months away.Steve
