I've opened a thread on the pfsense board under Installation & Configuration (top forum).
Search Sky on there.
It's the dhclientp.conf file IIRC that needs to be modified, however I can't comment until I've got the fibre installed.
OK I figured it out in respective of MER.
You first need to setup your modem to vc-mux bridged. I currently have a draytek vigor v120.
Draytek Vigor 120 ADSL2+ modem. Settings for that are: MpoA page: MpoA Enabled, Encapsulation: 1483 Bridged IP VC-Mux, VPI 0, VCI 40.
You then need to plug in your sky sagem modem/router and retrieve your LAN MAC, IP ADDRESS AND IP GATEWAY. YOUR SUBNET IS 255.255.255.0/24
with this information you can now apply that to any router or hardware firewall.
This method also works with fiber I am told, but you don't need to configure the open reach modem. All that changes is that your plug the openreach modem into the sky router and retrieve details as normal.
The method is simple and does not require username/password **** as pppoa does. Ive read that sky are phasing out the pppoa for MER.
Only questions regarding this method for me are the following:
Will the ip dchp lease will expire ?
potential of being stuck with a static ip, which depending on peoples scenario can be bad or good.
