I was not quite clear on the configuration I'm trying to achieve

   |---------|    |---------|                        |-------|
---| ADSL    |----| W2003 S | ( ----| PC's  |
   | router  |    | DHCP    |                        |-------|
   |---------|    |---------|
                  |---------| (
                  |  LAN    |   none bridged
                  | Mono 1.2b7
                  | Atheros |
                  | miniPCI |
                  |  WAN    | ??

                     Laptop A (DHCP client)
                     Laptop B (DHCP client)

The Lan I have given a static IP adress, as this is the only option, The
WAN side I have chosen DHCP, with gateway The block
private networks is unchecked. The DHCP relay is on and has
as server configured. The DHCP server on the monowall is switched off.

I have browser access from my internal network to the monowall, I do not
get an IP address from the Laptop through monowall, nor can I ping the
monowall from the laptop, after changing the configuration to a fixed IP

Now I cannot find in the FAQ nor the message board what to do next. 
How can I get the DHCP relay working through monowall ?
Do I need to make additional rules in the Firewall ? 
NAT-rules ? 

Any help appreciated.

Best regards,
Hans Ruck

Clear the "Block private networks" on the WAN interface page if you need
private IP (private networks as per RFC 1918 i.e. 10/8, 172.16/12,
192.168/16) on WAN... 

Inbound NAT of services will be a bear, unless the ISP does some NATing
for you. Keep in mind that double NAT is icky...

Back to the original question - of DHCP. If you run your own DHCP, just
give out the m0n0wall LAN IP as the gateway/router address. That is what
I do - Scope option "003 Router" is m0n0wall LAN IP. Don't forget to
disable the m0n0wall DHCP - Windows DHCP service will not start if there
is an existing DHCP on the network (broadcast domain). If you are
running an Active Directory, give out the Windows Server as the DNS (you
can use the m0n0wall as a forwarder for the Windows Server).
