I have a problem with DHCPD and WPAD. The OpenBSD version is 4.4.

The error message is (in /var/log/messages):
Nov 17 13:14:35 gw dhcpd[5096]:         /etc/dhcpd.conf line 12: no option 
named option-252
Nov 17 13:14:35 gw dhcpd[5096]:         option option-252 
"http://wpad.domain.local/wpad.dat "

* In older versions of OpenBSD the same line works fine
* The problem seems to be with the option-252. If I change the number to 251 
or 253, there is no error.
