O.K. I tried now with 2 NIC but i got this error:

Multiple interfaces match the same subnet: nxge0 nxge1
Multiple interfaces match the same shared network: nxge0 nxge1

i have two interfaces (IPs) in the same subnet.

nxge0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
        inet netmask fffffff8 broadcast
        ether 0:14:4f:f3:32:cc
nxge1: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 3
        inet netmask fffffff8 broadcast
        ether 0:14:4f:f3:32:cd

do i really need to have different Vlan for each interface to make the
dhcp works? i only require the server for remote users (not on the
local subnet).

i tried many options including server-identifier/shared-network
without success. the conf in the two looks like:
ddns-update-style none;
shared-network "local" {
subnet netmask { }

any help is appreciated.
