DHCPD, Multiple interfaces, Single Subnet

I have an OpenBSD 3.7 firewall with five network interfaces on it, one of which is connected to the Internet. I'd like to use the remaining four interfaces as a network switch for a single internal subnet. The main problem I have is that the DHCP daemon doesn't like multiple interfaces matching the same subnet. I've tried bridging the internal interfaces and running dhcpd on the bridge, but it gives the same error.

Any ideas, anyone? Smilie

ifplugd.conf(5) 						File Formats Manual						   ifplugd.conf(5)

NAME
ifplugd.conf - ifplugd configuration file SYNOPSIS
/etc/default/ifplugd DESCRIPTION
ifplugd.conf is the configuration file for ifplugd. It is a shell script that is sourced by the init script starting the daemon. It shall be used to set environment variables which are interpreted by the init script: OPTIONS
INTERFACES Specifies the ethernet interfaces to monitor. It has to contain a space seperated list of network interfaces names. Most users will probably use "eth0" here, however you may add additional interfaces for monitoring more than one device. A special value is sup- ported as well: "auto" will enable a more or less working auto detection of available network devices. This won't make you happy when using network module auto loading, since it cannot detect currently unloaded network devices. HOTPLUG_INTERFACES Specifies the interfaces that can be hotplugged (like interfaces on PCMCIA, USB or WLAN adapters). "all" can be used to make the udev script start an ifplugd process for any hotplugged interfaces (except those already listed in INTERFACES). ARGS Additional command line arguments for ifplugd invocation. See ifplugd(8) for further information. ARGS_iface If specified for an interface this variable takes precedence over ARGS. This may be useful if more than one network device is present. SEE ALSO
