+## 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.cfg
+## 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           nobody
+group          nobody
+
+## 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.

+
+
+######### 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
+
+
+## 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
+
+
+## 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
+
+
+######### 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
