If I delete the ppoe wan service, I lose all internet.    Im at a bit of a loss now, the NF12 either doesnt support what im trying to achieve or im completely messing it up. After following what you said below a few times the NF12 accepts it (screenshot attached) but as soon as I set the UDM Default WAN setup to manual (which is required to enter the VLAN ID it loses connection to the outside internet. ...

Ok, so I tried the bridging setup and rebooted both devices, and UDM lost external connection.  One question I have with that is on the NF12 are both WAN service connections still required or does one replace the other. Even though it didnt work I think I want to try it again.    As for the direct connection I will have another play with that also when I get some time, I think that I may need to factory reset the UDM to enter all the ISP details in as I dont seem to be able to edit those details.      ...

Ok thanks, that provides a few options to try, there are a few articles saying that I cant use the UDM as a modem for TPG service, (http://www.htgsd.com/information-technology/networking/how-to-set-up-a-ubiquiti-unifi-dream-machine-udm-with-vlan-pppoe-tpg-etc/) So I might skip that option.    I have already tried the port forwarding using ports that the UDM VPN service using only difference from your description is that I havent set it up as a static, ie the UDM address is dhcp assigned but it it the only host on that network.    I have looked at the NF12 manual and it only has options for wireless bridging which I understood to be a different feature.   The UDM does support VLAN ID, and I can create a new WAN connection on the NF12 not real sure how to set this up though, is it a specific vlan id for both UDM and NF12 (from TPG). I am unable to edit the vlan field on the existing wan connection on the nf12 ... View more

I kinda tried that before with no luck, There was also few forum posts that said the UDM couldnot directly connect to Australian NBN boxes. I changed the wan connection over from the NF12 to the dream machine and waited a while (no reboot) and nothing so changed it back, I gues now that you have mentioned it should work a reboot would be worth a try.  Essentailly I am trying to use the VPN feature of the UDM but my WAN IP on the UDM is the DHCP address assigned by the NF12 which wont work because it isnt routable.  ...
