DHCP client not getting IP address from Time Warner

[Ask Bjørn Hansen]

Hi everyone,

After years with Speakeasy at home I'm trying out Time Warner Cable  
(we live too far from the CO to get good DSL speeds).

On OS X I plug-in and get an IP from their DHCP server:

On FreeBSD their DHCP server seems to just ignore me (but I see lots  
of broadcast replies to 255.255.255.255/ff:ff:ff:ff:ff:ff).  I've  
tried with both the standard dhclient and the isc dhclient from ports.

00:00:24:c9:23:c1 is my FreeBSD box (Soekris 5501 with vr ethernet):

The OS X dump was made with dhcpdump 1.7 and

sudo tcpdump -i en0 -s 1518 -lenx port bootps or port bootpc | ./ 
dhcpdump

The FreeBSD one with "dhcpdump -i vr1".

Below is a tcpdump of one of the DHCP requests.

Any ideas would be greatly appreciated.
