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

Cisco 2800 router
FE1 172.16.32.2 255.255.255.224

interface FastEthernet0.32
 encapsulation dot1Q 32
 ip address 172.16.23.33 255.255.255.224
 no snmp trap link-status
!
interface FastEthernet0.96
 encapsulation dot1Q 96
 ip address 172.16.23.97 255.255.255.224
 no snmp trap link-status

interface FastEthernet0.128
 encapsulation dot1Q 128
 ip address 172.16.23.129 255.255.255.224

interface FastEthernet0.160

Add this clause IP nat inside, I dont see any translation from that interface. Also it would be nice if I see your router config.
If you want all the interface to participate on the internet give to all of them the same clause.

Interface FastEthernet0.32
 encapsulation dot1Q 32
 IP nat inside
 ip address 172.16.23.33 255.255.255.224
 no snmp trap link-status

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.
