:> essentially receiving an "unfiltered" stream from the adsl.
:> This worked good.
:>
:> But I wanted to see if I could get a little closer to the adsl
:> acting as just a modem. I set the adsl in "transparent
:> bridge mode". This basically just passes the data thru to the
:> wireless, using the WAN ip, which is resolved in the wireless
:> router by DHCP. Then this router handles everything and
:> I use dhcp to accept the clients. This works for me,
:> because the adsl modem uses dhcp to connect to the
:> ISP - not sure if/how it would work if your using some other
:> mode such as PPPoe.
:>
