Cisco router behind a Linksys BEFSR41 router

[matmanscott]

I have a Linksys BEFSR41 router used for my internet connection. I have a pc connected to it working fine. I also have a Linksys 8 port switch connected to the router and a two pcs connected to the switch. All works well.

I just got a Cisco 1605 dual ethernet router. I connected e0 to the Linksys router and e1 to the switch.

I can ping everything from the Cisco router. I can ping everything from the pcs connected to the Cisco router/linksys switch, including the Linksys router IP address, but cannot access the internet. Also, I am unable to ping the pc directly connected to the Linksys router. I am puzzeled?

Ideas anyone??
