Hi,

What you want to do is very easy. Although I am not certain the
existing ADSL router you own can be told or configured to be a dumb
bridged ADSL modem, much like the Linksys ADSL2MUE units are by
default. All this means is that the linux box would run PPPoE and do
the authentication etc. Then you'd install and configure NAT (Network
Address Translation) so that your internal lan can see and use the
internet. Much like NAT built into the WAG54G, but in this case the
linux box could handle more NAT entries and not fall over when too
many are opened. etc.

Take a look at one of the ip-masquerading howto guides that use to be
found on one of the Linux Documentation Project mirror sites. I am
guessing its probably been rewritten and maybe called something else.

Although I suspect at the moment, your WAG54G probably is not going to
be able to be a bridged/dump ADSL ethernet modem. ie. not going to be
able to disable nat, dhcp and all the other functions that make the
device it is.
