Second ethernet without router?

[Steven Buehler]

	I have several servers running on public IP's all on their eth0's.
They of course have a router -> switch -> servers.  I would like to setup a
local net on the eth1's of each server, but I don't have a router.  Just the
switch and servers.  I must have goofed something up pretty bad because I
setup the eth1 on one of the servers to have an IP of 192.168.1.1, Mask of
255.255.255.0 and gateway of 192.168.1.1.  The second server was an IP of
192.168.1.2, Mask of 255.255.255.0 and gateway of 192.168.1.1.  After doing
an "ifup eth1" on each machine, the public IP's on the eth0's can't be
reached any more either.  Do I need to have a separate router and switch to
do this?

Thanks
