lnc0: dhclient assigns address, but non reachable

Hi!

dhclient assigns an address to my freebsd 6.0 current system, but
then this system does only reach other systems on the local network
if they are within the same subnet.

"netstat -r" delivers:
netstat: kvm not available
Routing tables
rt_tables: symbol not in namelist

any idea what to do, to make routing work?
