That is strange, unless the interface connecting to the router is
something other then eth0.

I would let the router act as the gateway, NAT, and firewall. You do
not want to double up the gateway, NAT, or DHCP server. You may want
to have a firewall running on all your machines. It adds another
layer of security.

If you are using all static IPs, then it does not matter if you run
a DHCP server at all. On the other hand, you may want to consider
running the DHCP server on the Linksys, or a machine that is up
24/7, and set up fixed IP assignments based on the MAC address of
the machine requesting the lease.

One other thing to keep in mind - you are probably going to want to
change the name server IP address - ether to the Linksys router, or
to a machine on the local network running a caching name server. (I
like the second method, because you can have hosts on the local
network resolve.)
