Router – configure pppoe on wrt54gl(openwrt)

dslopenwrtrouter

I have home DSL connection from my ISP with a beetel modem at my end. I want to make my network wireless, so i bought a linksys wrt54gl and installed open-wrt on it. My ISP provides dynamic IP's with me connecting via pppoe. My question is how do I configure openwrt to work with this. Please suggest what option should I go with, or any other you recommend.

DSL cable–>Beetel Modem–> Wrt54gl in bridge mode with beetel modem doing the pppoe and having a DHCP server.
DSL cable–>Wrt54gl with wrt54gl handling the pppoe.

Is option 2 possible, can I have a setup without bringing the beetel modem in the picture at all?

Best Answer

You can't do #2 because the wrt54gl doesn't have a DSL modem built in. You can't plug a phone line into an Ethernet jack and have it work. However, you might be able to put the beetel DSL modem into bridge mode, letting the wrt54gl handle PPPoE, NAT, and DHCP service. That's probably the way I'd go. Do you have the ability to reconfigure the beetel modem?

Router – Trouble setting up a DD-WRT router with a DSL gateway

You want to put the router between your gateway and the switch as mentioned. In this typical setup, all traffic between the internet and your local network runs through the router and gateway, which allows you to control the traffic using either device.

internets---------[gateway]---------[router]------[switch]---local network
              192.168.0.1 (lan)   192.168.1.253              192.168.1.XXX
              XXX.XXX.X.X (public)

Your second setup could allow all connections through the gateway, but this would mean that you would not be able to force control traffic from your router and your router would just be a DHCP server.

internets---------[gateway]---------[switch]------[router]
             192.168.1.254 (lan)       |       192.168.1.253
             XXX.XXX.X.XXX (public)    |
                                       +---local network
                                           192.168.1.XXX

There is a third possible setup and one that I actually use at my place. In this mode, the DSL modem only acts in a pass-thru/bridge manner (like a dumb modem). We use PPPoE for DSL connections and DD-WRT supports it. As a result of this setup, the Internet connection interface is actually on the router instead of the gateway, which allows further control over the traffic.

internets------bridge---------[router]---------[switch]---local network
               (modem)     192.168.1.254 (lan)              192.168.1.XXX
                           XXX.XXX.X.XXX (public ip)

Nat – How to avoid double-NAT with Netgear VVG2000 VDSL router/modem

You're on the right track with A. You want to disable DHCP, DNS, NAT, and everything possible on the Netgear VVG2000 and put it in bridge mode.

The parameters on your modem, like VCI and VPI and such, need to be the same on your D-Link.

Sounds like the issue you might have been having with A is that DHCP wasn't disabled on the VVG2000?
