PPPoe and Static Ip Addresses



  • I have been searching everywhere (including this fourm) but had no luck finding out how to setup pfSense with PPPoE and Static ip addresses, so I am hoping I can get an answer by one of the genuises in here.

    I am totally new to pfSense.

    What I need to do is to configure my router (Yawarra box using pfSense) to use PPPoE and get the static ip address(es) that have been assigned to me.

    When I select PPPoE I can only enter the username and password and then I get a dynamic ip address. If I select Static IP address I can obviously not enter username and password for PPPoE.

    The service is from AT&T and the modem (Motorola 3347) has been set in bridged mode.

    Someone please help.



  • I don't know about your service, but its possible that you have a "static" IP address which is set through PPPOE. The address is "static" in that the ISP always gives you the same address but the ISP tells you the IP address through PPPOE.

    I suggest you check with your ISP if thats how their service works.

    wallabybob has the right idea for how most ISPs do this, at least in the region where I work.

    When one of our customers needs a static IP, we assign it on our end in the user database and when they connect, it's passed back to them via their PPPoE login. No need for configuration on the end user side at all.



  • Hi ugys thanx for your input. I am in Florida right now and the AT&T do not assign the static ip address through the PPPoE username and password (god knows why). They have provided me with a Motorolla Modem/Router where I have to setup the LAN ip address of the modem to the static ip provided. This is how they do it. IS there anything similar that can be done in PfSense?



  • I have a client in Houston, TX that uses AT$T DSL with a static IP.  Using a 2Wire 2701 modem.  The modem is not in bridge mode but it is set to DHCP and always pulls the correct static IP assigned to him with just the user ID & pw put in the modem.  I was just going through a couple of Motorola modems from AT$T that I had replaced at clients sites due to the recall (they work until they heat up) and I can't see a model number on them so I'm not sure what I've got here to test with.  If I can get over the flu before the weekend I'll take one with me to the site this weekend (normal maintenance) and try it out in your config.  It may just be the difference between AT$T and the company formerly known as BellSouth in the way they manage their network.

    What you describe is a modem in "half bridge" mode. It's doing the PPPoE login and then handing off the static IP via DHCP locally.

    It should work just as well if you put the login info directly into pfSense and had a plain modem/bridge on the line.

    It's AT&T up here, too, and it works the same way.



  • HGi Jimp,

    Jup that is what I ended up doing. I just let the modem login with PPPoE and then let pfSense handle the rest. It is just a shame the way AT&T does this. Why they have to be so difficult? Anywaz, thank you all for your inputs. It really helped me.
