Upstaires:
Thanks for comment. I am new to Linux, so some questions appear too newbie.
I have 2 DSL modems, one with ethernet port, one with USB port without ethernet. If it works as what you said, so how about the latter one(USB modem)? Will it work as well?
It's a Speedstream 4060 modem, pretty old products from Efficient,come with driver for windows,do I need to find a driver for Linux?
By the way, how to configure PPPoE in Linux, is it as easy as just provide UserID/Password, plus something like DHCP?
Thanks
