I have a Zyxel Prestige 645M ADSL modem and I'm trying to use it in Linux with rp-pppoe client program. Is anyone using this modem in Linux? If so, could someone please send me their kernel configs and/or extra settings.

My kernel config includes ip_gre, PPPoE, and all related stuff.
Still, when I try to connect, I get “Error sending PADO packets”, and sometimes LCP_config errors.

I've tried to sniff the Windows connection from Linux box using eth0 in promiscuious mode, but the pppoe sniffer doesn't get anything.

Thanks a lot for your help.
