I've set one up like this:

+--------+      +------+    +-----------+      +----------------------+
| router |-------| FW |-----| linksys |-------| ethernet switch |
+--------+      +------+    +-----------+      +----------------------+
   Internet                    LAN

My router & firewall had 192.168.1.1 and .2
The LAN was 10.0.0.x

The firewall did NAT.
   It also served to the LAN:
DHCP to the linksys & everything on that side

The linksys did not do DHCP.
I did not use the 5th port on the linksys.  If I did, I think I chaged it so
it was on the same lan as the other 4.  The linksys was a v2.2 wrt54g
