how to direct traffic DNS to other routers

Hello I am sort of new and need some assistance please. I have setup intervlan routing which works and able to ping and connect to my subinterfaces but I cannot access the internet from any of those networks. My setup is the following. I have 2 routers as the office is using a SOHO linksys router where I have configured static routing to point toward a 2800 series gigabit router which has 4 sub interfaces on one of the ports. The linksys router is connected to the isp. The cisco 2800 is connected to the linksys and internally.

How do I get the cisco 2800 to point to the linksys for internet access. I am using static routing (which works fine). I have tried adding the dns address of the isp dns on the 2800 but that seems to not work. I am also open to setup a linux DNS server internally. Any links I can use.

LINKSYS ROUTER 172.16.32.1

Double natting,
Ip route 0.0.0.0 0.0.0.0 172.16.32.1 is missing

Not sure why you use the soho instead of connecting the external into the 2800 router...

I think if you draw a complete network layout it will become clearer what needs to be done.
You could bypass the linksys directly connecting its wan into the FE1 port...
Needing to setup access-listserver and nAT rules as referenced by hemil.
