I don't actually think my motives are relevant.
In case I didn't described the situation clearly,
my CentOS server is connected to an ADSL modem by ethernet (eth0).
The modem's IP address is 192.168.1.254 .

I have a second NIC on my server (eth1) 
and I want to attach my LinkSys router to this by ethernet,
to work effectively as an access point
(perhaps that answers your question?)
on a LAN 192.168.2.* .

I'd like to connect my laptop to the system with WiFi,
with an address perhaps of 192.168.2.3 .
The router might have the address 192.168.2.12 .

Neither of the above, if I understand you correctly.
I want to connect the router as described above.

The reason, roughly speaking, is that I want all data
that comes into or out of my system to go through the server,
where the traffic can be followed and monitored if necessary.

Do you have a LinkSys router with an IP address other than 192.168.1.1 ,
or even better with an address other than 192.168.1.* ?
If you have, could you tell me _how_ you did it, please.
I don't really care _why_ you did it.

The instructions on the router only explain
how to set it up (with address 192.168.1.1)
attached directly to an ADSL modem.
I could do that, but I don't want to ...
