I'm going to check if WinXP does the arping check.

But the other problem with a SOHO including a DHCP server is that a SOHO 
is often rebooted (because the user changed settings which require a 
reboot, because of a power failure,...).

So each time it reboots, the lease file is cleared.

I have the issue only in this case: the SOHO reboots, the WinXP PC 
(firewall enabled) has 192.168.1.20, the Linux PC also has 192.168.1.20, 
and in the lease file of dnsmasq, 192.168.1.20 corresponds to the MAC 
address of the WinXP PC.
