Hit a crazy one today that I can't figure out.

My laptop is set to use DHCP for both lan0, wired, and lan1 WIFI. Normally it
is plugged into my switch and gets a real IP address from that. Today I needed
to run a wintendo session in VPC in order to upgrade the firmware in another
box - but there are no spare addresses on the switch. First I tried VPC without
virtual switch, but that barfed because the upgrade process expects the PC
doing the upgrade and the box to be on the same subnet.

So, having another subnet floating about :-) I first changed the address on the
box, rebooted it and plugged it into the other subnet and also moved the laptop
cable. Now on this subnet DHCP is supplied by a Solaris box. Nothing. DHCP just
sat there. 

To check out it was serving up addresses I powered up my WIFI box which is on
the same subnet and uses DHCP, albeit with a "fixed" address. Got an IP no
problem. Switched the laptop to WIFI - gets an IP. This of course is no help as
Virtual switch won't work on a WIFI card.

So, in summary, DHCP won't work wired to the Sparc, but it will work through a
WIFI box that is passing it on wired to the Sparc.

I ended up turning the WIFI box to fixed IP and turned on *it's* DHCP and all
was fine. Trouble is I can't use this setup for real because the stupid box,  a
DWL-700AP, has nowhere to set the DNS address to hand out.  

I am *sure* I have successfully used the Sparc to serve addresses in the past.

Any thoughts?
