[NTLUG:Discuss] Routing question

[Jack Snodgrass]

I think that I've done this in the past, but I can't seem
to figure out how to make it work now. 

I've got a box with two NIC cards: 
192.168.100.1/255.255.255.0
and
192.168.200.1/255.255.255.0

I've got a second box that has a single NIC card
192.168.200.2/255.255.255.0
and I want it to answer for 
192.168.100.200/255.255.255.255.

So I want anyone on the 192.168.100.0/255.255.255.0 network 
to route traffic for 192.168.100.200 via 192.168.100.1 but 
I don't want to add a static route on every 192.168.100.x 
PC for the special 192.168.100.200 route that goes via the 
.1 box. 

I have the 2.2.19 kernel. 

I thought that I could do a arp publish for the .200 box 
on the .1 box but that doesn't seem to work. 

Does anyone know what I'm doing wrong?
