Simple Routing using FC2/3

[Todd Wohlwend]

This should be a simple task.  I need to use a FC2/3 as a router.  (I have 
done this in RH7.2 with no problems)  Here is my senerio :

Fedora C3 (soon to be router - I hope)
External Interface 172.16.176.152 / 20
Internal Interface 192.168.213.152 / 24
No GW on internal
net.ipv4.ip_forward = 1 set in sysctl.conf file (rebooted of-course)

Internal PC
IP = 192.168.213.253 / 24
GW = 192.168.213.254

I can ping the 192.168.213.254 and 172.16.176.152 from the internal PC, but 
not any device in the 172.17.176 network.

This is a full install of FC3.  iptables is default.  I have even disabled 
iptables to test. Still no luck.........I need a simple solution.  I do not 
want to disable iptables and install another product.....like firestarter or 
enable (masquerading) NAT.

There must be a simple solution?
