Using a router as a PPPoE as a passthrough

[blackbird307]

I am trying to bridge a modem capable router onto another router, I am also using PPPoE to connect to the internet. Router A has PPPoE passthrough, if I enable that, is there anything else I need to do? Will I have to disable DHCP and Firewall on it? I made router B have the same settings as router A. The reason why I am doing this is because the current router is operating as a modem aswell, but it lacks important, needed features, ie port forwarding. I don't want to have to purchase another modem.

I have never done something like this before.

Thanks!

You dont need PoE you need to disable DHCP settings, However you will need to have a cable plugged into the Wan port or Ethanet Port its up to you if your running a local network but if its just to get better internet or ther features like you have stated then i would just plug a cat 5e cable into the wan port and the connect it to the ethanet port in router B and then from that connect your other devives

When you set the router to bridge mode the whole concept of DHCP and anything else related to IP is gone. The device is running purely at layer 2 and has no concept of ip. Likely the firewall will be disabled also because although it is possible to run a firewall in transparent mode I doubt a consumer router would have that feature.

I have multiple computers on the network so I will for sure need an additional router.

One more quick question. Just to be clear, RFC 1483 Bridged is essentially the same as PPPoE pass through? I have no idea why the router is giving two options when they are supposedly the same thing. Also, the firewall no longer functions when this mode is configured aswell right? Ill disable it anyways.

Thanks again

I don't think they are exactly the same RFC1483 is considered transparent bridging. I forget what pppoe pass though is. From what I think I remember the different is related to PPPoA which is what is really being run on a dsl connection.

I would try one if it does not work try the other.

So I finally enabled Router A to have PPPoE passthrough to Router B so I could forward ports to another device on the network (since Router A isn't capable of port forwarding). The result was that it made absolutely no difference. I still cannot connect to the webserver.... I can connect to it locally, but not remotely. The PPPoE passthrough feature was completely useless. Anyone have any idea?

I have 4 other options:
PPPoE --- Already tried bridging through here, and Passthrough
PPPoA
RFC 1483 Transparent Bridging
RFC 1483 via DHCP
RFC 1483 via Static IP

with DSL you have to have a modem. the modem is where the magic happens and you can go from rj11 phone cable to rj45 network cable.
you can still configure the modem in bridge mode and still have the router establish the PPPoE connection but you need the modem to do the modulation / demodulation part.
