dhclient and ADSL modem trouble...

[Digital Brain]

>You sure the ISP doesn't use PPPeE?

The modem acts as a bridge. All I have to do is turn it on; it then 
synchronizes with the ISP's network (PPPoA). Then I just execute dhcpcd eth0 
from the linux machine (connected to the modem) and I'm assigned an IP and a 
default gateway in mere seconds.

Unfortunately, as simple as it is in linux, it doesn't seem to work with 
freebsd...
It should have worked with dhclient ed0, but the dhcp server's reply gets 
lost somewhere.
