Linksys routers can't provide a DNS hosting function, _per_se_ -- in 
their default configuration, they just proxy DNS requests in and out -- 
but they *can* provide a different DNS resolver address to their DHCP 
clients other than themselves. So, I'd suggest setting up your Linux box 
as (mostly) a caching/iterative resolver (all you need for that is a 
valid hints file), point all of your internal clients to that box for 
resolution, and then set up and host "internal" versions of your 
web-hosted zones from that box. For security's sake, if you ever 
port-forward DNS to your internal nameserver (e.g. if you "DMZ" it), you 
would want to limit the clients that can query and/or recurse to only 
your own address range(s).

P.S. I tried to verify some of the above on Linksys' website, but 
apparently their web server(s) are down right now (500 error -- 
"RESOURCE_RECLAIMED"????). So I'm just speaking from memory, as an owner 
of several Linksys routers over the years...
