>Description:
By default, isc-dhcp3-server is compiled with jail support, however it makes
non-jail operation not workable. This is not mentioned in pkg-message or when
options are presented.
This presents an unforseeable problem, where one wants to make sure a configuration works and then optionally move it to a jail (quite standard behavior).
It is possible this situation is only present on systems with multiple interfaces, judging from:
http://lists.freebsd.org/pipermail/freebsd-questions/2007-September/157107.html

>How-To-Repeat:
Install net/isc-dhcp3-server with -DBATCH or accept default options.
Create a normal config and start dhcpd, either via dhcpd <interface> or using /usr/local/etc/rc.d/isc-dhcpd start
Connect a client to get an IP. Client does not receive it, possibly because
information is sent out through the wrong interface, even though log shows:
Sep 21 11:35:41 squeeze dhcpd: DHCPDISCOVER from 00:19:d2:60:be:a3 via ath0
Sep 21 11:35:42 squeeze dhcpd: DHCPOFFER on 192.168.1.150 to 00:19:d2:60:be:a3 (rachie-PC) via ath0

<repeats until client gives up>

These two lines are no different from a working installation:
Sep 23 06:46:44 squeeze dhcpd: DHCPDISCOVER from 00:19:d2:60:be:a3 via ath0
Sep 23 06:46:45 squeeze dhcpd: DHCPOFFER on 192.168.1.199 to 00:19:d2:60:be:a3 (rachie-PC) via ath0
Sep 23 06:46:45 squeeze dhcpd: Wrote 1 leases to leases file.
Sep 23 06:46:45 squeeze dhcpd: DHCPREQUEST for 192.168.1.199 (192.168.1.1) from 00:19:d2:60:be:a3 (rachie-PC) via ath0
Sep 23 06:46:45 squeeze dhcpd: DHCPACK on 192.168.1.199 to 00:19:d2:60:be:a3 (rachie-PC) via ath0
Sep 23 06:46:48 squeeze dhcpd: DHCPREQUEST for 192.168.1.199 from 00:19:d2:60:be:a3 (rachie-PC) via ath0

>Fix:

Untick default selected options. Most likely using paranoia option still works,
but I haven't tried this.

NOTE: configuration file dhcpd.conf was not changed between not-working/working situation. Port was simply recompiled using `make rmconfig' and portupgrade -f.
