That's enough tinkering for tonight. I'll play about with it for the next few days. Currently still waiting to see if the D7000 trips over once it reaches the time it normally falls over before removing the modem side of it for the Zyxel.
I've set it up following all your settings Spring and made a backup of my config now. Hopefully it will just be a case of plug in and then sort out the Netgear to deal with the routing side.
Can someone confirm this?
Gone into Broadband settings and changed to bridge, VLAN active and left 802.1p at 0, Changed 802.1q to 101 (Is that correct??)
