Ah yes - forgot that titbit of information - :(.

In that case, what you need do is connect the Linksys to the same switch 
as the one which hosts your eth1 and ADSL modem.  Go to the 
configuration pages on the Linksys, change the IP and subnet, then when 
you commit and reboot, disconnect the ethernet cable from that switch 
and onto the switch your LAN is connected to.  Then on your browser, 
reconnect to the new IP and continue to configure whatever else you need.

Remember to disable DHCP on the Linksys.  However, if you want to 
identify users using the AP, then you can create an exclusion range in 
your CentOS DHCP and dish out that excluded range from your Linksys DHCP.
