FC4 - Firewall/Router

[Greg Swallow]

Ha, finally figured out it was the 20x - 48x IBM CD-ROM drives causing 
the problems in my installations of FC2 and
FC3. Not IDE DMA.

Now have FC4 and have reconfigured my farm and am at the point of 
needing to setup a firewall. No GUI to find, or
I missed it during modified Workstation install, to configure firewall, 
DHCP, and routing. Have done this the hard way
before, but need a few pointers to get me in the right direction again. 
The last time I did I could never get a continuous
hole in my firewall for access; had to shut it down to be able to route.

So I am editing dhcpd.conf and the .conf files for each NIC in the 
firewall box, but iptables has me puzzled.

What I'm trying to setup:

Network 192.168.0 is configured by D-Link wireless router to cable 
modem. firewall has access to the internet through
the router via dhcp on eth0. eth1 is attached to what will be network 
192.168.1 and we want firewall to serve dhcp on
that network. We also want firewall to route internet traffic from/to 
192.168.1 through 192.168.0; without having to
shutdown the firewall server to do so.

I know it is possible and I've come close, but had to set it aside so 
that I could complete other projects.

Thanks in advance for any help you folks can provide, suggest, or offer.

God Bless,
