Router software and Windows XP Pro SP2 Firewall

I have a machine here that I am trying to set up as a router.
The external NIC has a fixed address, assigned by the company.
The internal NIC has address, 192.168.0.1.

The machines on the internal network, work fine and get there IP addresses
from the router machine when the Windows Firewall is turned off. When I turn
it on, the machines can no longer get their address from the router.

Looking around the Firewall setup panels, I can not see anything that
controls this.

Can someone point me in the right direction to open the correct port (547?)
for DHCP on the internal NIC only?

Do yourself a favour and get a cable/DSL Router such as the Linksys BEFSR41.

Circumstances dictate the use of this machine, as it has other jobs to do as
well.

The machine can still do its jobs and it won't be taxed by additional overhead.

My advice still stands.

Stephen,

You *may* be able to do this by opening the Windows Firewall in
Control Panel, click the Advanced tab, click the Settings button for
the LAN, then click the Add button. Have never attempted this so,
YMMV.
