## This file contains a sample configuration for the network shown
## below:
##
##  --------------              ----------              -------------
## |  DHCP Server |            |          |            |             |
## | 192.168.8.66 |------<eth1>| dhcp-fwd |<eth2>------|   Clients   |
## |              |            |          |            |             |
##  --------------              ----------              -------------
##
## By default, the dhcp-fwd agent looks at $(sysconfdir)/dhcp-fwd.conf
## for this file. By using the '-c' option when calling dhcp-fwd, this
## path can be changed.


######### ENVIRONMENT SETTINGS #########
####
###
## The server will drop its privileges and goes into a chroot-jail
## after doing its initialization. The following parameters are
## defining the needed parameters:

## User and group names/ids. It can be a numeric id or a resolvable
## alphanumeric-name.
##
## WARNING: when compiled with dietlibc the user-/group-names must be
##          resolvable by files-NSS. LDAP or NIS NSS will not work so
##          the numeric ids must be used
user		dhcp-fwd
group		dhcp-fwd

## chroot() path
chroot		/var/lib/dhcp-fwd

## Logfile and loglevel. The logfile-location is relatively to the
## directory where dhcp-fwd was started and not to the chroot-directory.
##
## The loglevel option is not supported yet.
logfile		/var/log/dhcp-fwd.log
loglevel	1

## SysV pidfile; contains the PID of the daemon-process and will be
## written with root-privileges
pidfile		/var/run/dhcp-fwd.pid


## Set limit for resources. When using much interfaces or servers
## below you will need to increase some values. Same holds when not
## using dietlibc. Use '-1' as the value to disable the upper limit
## for the given resource.
##
## Look into /proc/<pid>/status to find out the real usage of the
## resources.
ulimit core	0
ulimit stack	64K
ulimit data	32K
ulimit rss	200K
ulimit nproc	0
ulimit nofile	0
ulimit as	0


######### INTERFACE SETTINGS #########
####
###
## The interface where the forwarder listens for messages. There must
## be specified BOTH the server-side and client-side interfaces!
##
## Each interface will be identified by its system-wide name
## (e.g. eth0). After this it must be told whether there are
## clients and servers, and if it is allowed to send broadcast
## messages to clients. The bcast flags will be IGNORED when
## forwarding messages to servers.

#	IFNAME	clients	servers bcast
if	eth2	true	false	true
if	eth1	false	true	true
#if	$IF0	true	true	true

## Each interface can be given an RFC 3046 agent ID. The 'name' config
## option sets this value; if an interface is not specified here, the
## IFNAME will be assumed.

#	IFNAME	agent-id
name	eth2	ws-c
#name	$IF0	$NAME0

## Each interface can be given an specific IP to be filled into the
## 'giaddr' field.
##
## BEWARE: because the outgoing DHCP message will contain the "normal" IP
## address of the outgoing-interface in its IP-header, some additional
## work in the system must be done. You can e.g. add an iptables rule to
## the 'nat' table similarly to this:
##
## | Chain POSTROUTING (policy ACCEPT)
## | target     prot opt source               destination
## | SNAT       udp  --  192.168.0.6          192.168.8.66       udp spt:68 dpt:67 to:192.168.2.255

# ip	eth0	192.168.2.255
# ip	$IF0	$IP0


######### SERVER SETTINGS #########
####
###
## Definitions of the servers. There must be told the type ('ip' or
## 'bcast') and the address. When using 'ip', the address is a non-bcast
## IPv4 address (dotted, DNS-names are NOT supported); and when using
## 'bcast' servers, the address is an IFNAME.

#	TYPE	address
server	ip	192.168.8.66
#server	bcast	eth1

######### DHCP OPTION 82 - SUB OPTIONS #########
####
###
## Some Setups needs some special settings
## These suboptions are supported
##   5  Link Selection  RFC3527
##   11 DHCP Server Identifier Override RFC5107
##
## Interface is the name of the interface the DHCP-Request will arrive

#suboption eth2  5 192.168.0.1
#suboption eth2 11 192.168.0.1
