After struggle of several months, I succeeded to modify the guruplug as a PPPOE ADSL router,
which completely covers all functions of my home wired and wireless router.
Followings are the simple description:
*Debian Lenny + pppoe + shorewall
*eth0 (ppp0) connects to ADSL modem
* bridged ehe1 and uap0 as br0, and give it a local fixed IP address.
A very, very powerful router. Usually, such powerful router will cost, at least, ? thousand dollars.
My goal is to use it to monitor the connecting states of all computers connected my network, and
control those if necessary.
Hope this information will help you.
