PPPoE interfaces dropping out

I am trying to get an RB1100AHx4 working, which is replacing my Trusty RB1100AHx2, which has a faulty port, probably a dry Joint, I have copied all my scripts across and the configuration looks the same, I have checked all the menu and sub menus and they look the same, however I cannot get any data to pass through it and all my PPPoE clients keep dropping out, I can log on to it, by setting a static IP, no data will route through it, I have checked the address assignment and the route setting and they are the same as my AHx2, the cables are in the same ports and the firmware is as supplied from factory but the 6.42.7 has been tried and 6.40.9 has also been tried and the problems are the same.

Just put here your config without private data.

Before I do that, I decided to export the full script from the ahx2 and remove user manger references, I reset the ahx4 with no default configuration set, then imported the script, it imports it but finishes wanting me to enter an interface, gone through the script not sure what interface it wants me to enter, so I tried ether1 and it come back with script file loaded and executed, problem is I do not know what interface it wanted me to enter, I did it again sane thing, this time entered ether11-gateway and it still worked.

How can I find out what interface it is asking for.
