Hello,

I have two machines running 9.0 and which use DHCP. The DHCP server is 
on a third machine using dnsmasq, also under 9.0, and provides an 
explicit default router address.

dnsmasq is sending the right stuff, as evidenced by the dnsmasq log on 
the one hand, and by the fact that a Windows7 machine and a Windows XP 
machine are using the same DHCP server and those machines get the proper 
default gateway info on the other hand.

Here is output from dnsmasq.log

Aug 27 16:32:19 dnsmasq-dhcp[922]: 4078691060 sent size:  4 option:  3 
router  192.168.4.1

What happens on the two FreeBSD machines is that I end up with no 
default gateway at all!

When the same DHCP server used to provide its default gateway (i.e. the 
machine dnsmasq is running on) everything was OK.

TIA
Bernard Higonnet
