PPPoE settings for BT Infinity with Netgear DM200 VDSL Modem



  • Hi everyone,

    I'm new to PFSense and I am struggling to configure PFSense to work with BT Infinity. I have bought a Netgear DM200 modem and set it to modem only mode (By default it is a one port router).

    I've entered the username bthomehub@btbroadband.com (This is the username that was on the original router) Password should be blank but PFSense doesn't seem to allow that so I have entered password.

    I've assigned the VLAN 101 to the PPPoE link and set the MTU to 1500 but the link won't come up.

    From reading the forum I know other people have achieved what I am attempting but I can't find the answer.

    Any idea's? What have I missed?

    My setup of PFSense is as follows;

    I have installed PFSense on Hyper-V configured a Gen 1 machine with three NIC's and created three external virtual switches (WAN, LAN and Wi-Fi) I have connected each NIC to a corresponding virtual switch.

    Thanks



  • I prefer to run the pfSense® software on its own dedicated hardware. When using PPPoE on WAN I have a real NIC in the computer exclusively for the WAN and I do not use a switch between it and the bridging DSL device. I use VLANs for all of the other interfaces on a separate NIC and PPPoE works fine with PlusNet. Maybe it would be useful to prototype your desired configuration on dedicated hardware before virtualising it.

    It's not clear how you're using VLAN101 there. It's not necessary to use VLANs for BT VDSL, have you tried it without?

  • I've installed it on the bare metal on the PC and it's still not working.

    Every router I've ever used has tagged the connection with VLAN 101. Is this not needed on PFSense?

    I have two VDSL connections here in the UK. One with BT directly and one with Plusnet. Both are using the BT Openreach modem and PPPoE connections from pfSense. No VLANs configured anywhere.

    It is possible I guess that the Openreach modem handles VLANs though I've not heard of that either.

    You have BT Vision or some other IPTV service on that perhaps? That might require a VLAN though I've not seen it.

    Ok, it looks like BT FTTC might need VLAN 101 but that should be configured in the modem not on pfSense.

    Steve



  • Only time I ever used a VLAN on BT FTTC was with a Vigor 2860, for my pfsense installs (BT, Plusnet etc) never used a VLAN. Connected with the BT Openreach modems and Vigor 130's

    I just put a space in password field for BT customers.



  • Just checked one of my installs, and I used -

    bthomehub@btinternet.com

    As login.


  • Netgate Administrator

    Yeah, I've never used a VLAN in pfSense and never had an issue connecting.

    The Vigor 2860 looks like it has a modem built in so potentially could have the VLAN configured on the VDSL.

    When you use the BT Openreach modem you're not using PFSense to make the internet connection the pre configured modem is. I am using a Netgear modem so PFSense has to do all the configuration of the PPPoE link.

    I could just use a router to make the internet connection but then you get double NAT and I don't want extra devices in the loop I want a router which in this case is PFSense and a VDSL modem.

    The BT Openreach modem is just a modem (technically it's a router in bridge mode but that's another discussion!). pfSense still runs the PPPoE session.

    The VLAN configuration for the VDSL connection is handled in the modem, pfSense doesn't see that. I haven't used that Netgaer modem but I would exp[act to set the VLAN there.

    Reading the manual for the Netgear it appears to have a VLAN ID setting there.

  • Hello,

    set the pppoe username as anything@btbroadband.com and the password can be anything your heart desires. Through my research the only time the VLAN is used is for BT when they use tr069 to configure their routers. (vlan 301 if i remember) dont worry about vlan 101 as it has nothing to do with what you're doing. I would imagine its for voip phones that connect to BT modems


  • Netgate Administrator

    VLAN 101 is usually required, for residential connections at least.

    If you're using one of the Openreach modems they are configured to add that. If you're using some other modem such as in this case you need to add it either at the modem or in pfSense if the modem passes that.
