Hi

Sorry if is'nt the right group, any network, dhcp, related group is blocked
here at work. :(

Im trying to boot a Sun Fire V240 on a different subnet than the boot
server. The boot server is running ISC dhcp. And the Cisco Router got
IP-Helper configured. But i get address already in use on the Sun Fire V240.
The dhcp config work fine if Client/boot server is on the same subnet. Must
i change something
on the config of dhcp? Tried specify boot net:dhcp,bootserver ip, and so
on. did'nt help.
Got any hints, things to check. Will post snoop output,dhcp log when i can
extract them somehow
from the console i use.

Trofors is SF V240 server (172.25 subnet) and 172.18.2.19 is boot server.
