Peter,

What exactly do you mean, "complaining about your subnet(s)"? Try starting 
dhclient with the -v option, and post the output please.

I recently had similar problems with FreeBSD 5.2.1. My network card was 
working fine, dhclient kept sending out DHCPDISCOVER packets, but no offers 
were received. The problem was caused by my cable modem: it cached the MAC 
address of the NIC of my regular computer, and when I plugged in my FreeBSD 
box things went wrong because it had another NIC. The problem was solved by 
clearing the cache of my cable modem. On most cable modems this can be 
accomplished by yanking out the power supply, waiting 10 seconds, and 
plugging it back in ;) .

I hope this helps,
Thomas
