I currently have the Vigor 130 setup in factory mode (pppoe pass-through) on a ubiquiti edgerouter, The router has the pppoe details in it and working fine for a internet connection.
Because the pppoe session in on the edgerouter the stupid thing will not report netflow information back.
Reading up on what I can find I think I need to put the vigor 130 into bridge mode with the pppoe details, will this pass the public IP address to the lan port via dhcp? so I can remove the pppoe session from the edgerouter.

I don't think that's a supported function; it's intended only for PPPoe passthrough.

How about I put it into router mode, and set a singel IP address on the DHCP pool and setup DMZ to that IP ?

Does the 130 sold in the UK have a "router" mode? Or maybe you're not in the UK....

I have just done a firmware upgrade and I cant not find router mode before or after.
So I guess that's a no.

The UK Vigor 130 is a modem only it has no other functions.
