Ok, lets ask something else.

1) How to config my dhcp server ( or put some rule in ipfw ) to deny 192.168.10.3 to be distributed/used from PC's in my network?

2) When 1 laptop is connetced to my wireless network, its take IP 192.168.20.34 ( becouse laptop MACs is not configured in dhcp server to take ip from 192.168.10.0 network ).So I run: ipconfig /release and ipconfig /renew
Now laptop wana take IP 192.168.10.3, but I put this IP manualy like 2nd in my network adapter, so laptop can take it and in cmd I have this msg:

Quote:
C:\Documents and Settings\PC_User>ipconfig /renew

Windows IP Configuration

No operation can be performed on Local Area Connection while it has its media di
sconnected.
An error occurred while renewing interface Wireless Network Connection : The DHC
P client has obtained an IP address that is already in use on the network. The l
ocal interface will be disabled until the DHCP client can obtain a new address.
Wireless adapter continue to reconnecting and after 1.40min he take IP 192.168.20.34.
Why my dhcp server say: "IP address that is already in use on the network" This IP is released and no one use it.Is there any options in dhcp.conf for releasing time?

ipw

IPW(4)							   BSD Kernel Interfaces Manual 						    IPW(4)

NAME

     ipw -- Intel PRO/Wireless 2100 IEEE 802.11 driver

SYNOPSIS

     ipw* at pci? dev ? function ?

DESCRIPTION

     The ipw driver provides support for the Intel PRO/Wireless 2100 MiniPCI network adapter.

     The Intel firmware requires acceptance of the End User License Agreement.	The full license text can be found in /lib-
     data/firmware/if_ipw/LICENSE.  The license is agreed to by setting the sysctl variable hw.ipw.accept_eula to 1.

     By default, the ipw driver configures the adapter for BSS operation (aka infrastructure mode).  This mode requires the use of an access
     point.

     For more information on configuring this device, see ifconfig(8).

EXAMPLES

     Join an existing BSS network (i.e.: connect to an access point):

	   ifconfig ipw0 inet 192.168.0.20 netmask 0xffffff00

     Join a specific BSS network with network name ``my_net'':

	   ifconfig ipw0 inet 192.168.0.20 netmask 0xffffff00 nwid my_net

     Join a specific BSS network with 64 bits WEP encryption:

	   ifconfig ipw0 inet 192.168.0.20 netmask 0xffffff00 nwid my_net 
		   nwkey 0x1234567890

     Join a specific BSS network with 128bits WEP encryption:

	   ifconfig ipw0 inet 192.168.0.20 netmask 0xffffff00 nwid my_net 
		   nwkey 0x01020304050607080910111213

DIAGNOSTICS

     ipw%d: device timeout  The driver will reset the hardware.  This should not happen.
