You can do this, funnily enough I tried this with an 1801 and a WRT.
You need to plug in the router to the linksys on the LAN port. Configure like this
Conf t
Interface faX/X
Description ## connects to linksys ##
IP address dhcp
This is just for your router to access the Internet. If you have a LAN off of your router You will need to do NAT.
Hope this helps

Thanks for you information.
when you mean " if you have a LAN off your router you need to do NAT" . If i have a LAN inside my 2600 router i wiil need to to nat translation.
also the WRT will not need any configuration?
thanks

Yes this is correct. WRT you can leave as default. I'll give you a quick example. Lets say our LAN in the router is connected to fa0/1 to a switch.
We will plug the fa0/0 in the linksys. We will configure like this:
Conf t
Interface fa0/0
Description ## link to linksys ##
IP address dhcp
Ip nat outside
!
Interface fa0/1
IP address 10.0.0.1 255.255.255.0
Ip nat inside
!
Ip access-list standard my_lan
Permit 10.0.0.0 0.0.0.255
!
Ip nat inside source list my_lan interface fa0/0 overload
Remember if you have clients that are on the LAN off of your router you will need DHCP too.
Ip dhcp excluded-address 10.0.0.0 10.0.0.10
Ip dhcp pool 10
Network 10.0.0.0 255.255.255.0
Default-router 10.0.0.1
Dns-server 8.8.8.8
Hope this helps

hello
thanks for everything.

Is there a requirement that the connected router also needs to get to the Internet?
If so, we just need add the network in the access-list for NAT, and have a default route on the other router outbound towards the linksys.
