yes exact - dhcp leases page

i have pfsense 2.0 beta 5 built on Wed Jan 12 23:13:34 EST 2011
and i have configured 12 machines - all are offline on status page from woL
(they are online !!! )
and when i ping they change status to online
i not wanted to test, if essetial function wake up functionally

i want that the machines shows the correct status

p.s. and when i have ping a machines of twelve..the pc looses dhcp lease and show status off after few minutes

but i have they configured with static ips and in dhcp leases shows me a dhcp pool adress for the machine

?
make i something wrong?
have they configured to dhcp - not static ips?
thanks for help
