    Sorry I misunderstood in a first step.
    Yes, with "Bridged Mode Only" you transform your Wag in a single modem....

    You'll need to first set the WAG54G from it's current setting to "bridged mode only." This means that "any" device configured behind the WAG54G has to now handle all PPPoA communications. The way around this is as so:

    Connect either a straight thru CAT5 cable or crossover cable (depending upon whether or not the WRT and WAG have built-in crossover ports) from one of the WAG's LAN ports to the WAN port of the WRT. Connect another cable from one of the WRT LAN ports to your PC. Log into the router and change it from DHCP to PPPoE.

    As you can see, this is soooooo not the right configuration to use with an ADSL (PPPoA) connection but I met someone who was able to do this. Basically, you now just need to put your ADSL account information into the PPPoE settings and this should be your workaround in order to use the WRT54G.

    The guy I got this little workaround from is using an ADSL2MUE in "bridge only mode" with a WRV54G set to PPPoE; additionally, the quickvpn utility for his remote users still works in this configuration. He's also on an ADSL connection, but using this little fix he stumbled across, he said that his connection is comparable to the proper configuration he was running before. So, I don't see a down side to this if it happens to work. Again, this is "not" how things should be configured, but if it works you'll be able to use your ethernet device!

    share wan ( ), turn of NAT (not sure if this is nessairy), relay dhcp to your wrt and you're done! what all you guys are trying to do with pppoe and pppoa i have no clue but i don't think you need to be changing anything on that end !


    there is no choosing unless your isp supports all, which i seriously doubt !

    It has worked, Ofloo. Yes, it goes against the same logic you and I may understand, "but" in the end, it's "all" a connection that can be terminated by an RJ45 connection.

    I wouldn't have believed it myself until someone explained to me how they were doing it. Hell, I may break my ADSL2MUE out and try this my damn self just to see if my ISP's connection may allow me to cross protocols "and" for firsthand experience. As long as the main connection (which is the ISP's PPPoA) is adhered to when the packet hits the WAN, what does it matter if a different protocol is used on the private segment up until it hits the public IP?!?!?

    It's all an ethernet connection up until the time the packet hits the wire...
