Getting internet to work from switch

[jpanzica747]

I am new to working with Cisco stuff and asking questions on here, so I hope I am asking this in proper form.

I have a Linksys home router, connected to a Cisco 3825 router, connected to a Cisco 3560 switch.

The router is working well and able to ping the internet with no problem. 

The switch is connected via port G0/1 on the router and f0/1 on the switch.

I cannot connect to the switch in any way from the Cisco 3825 router, however I do have VOIP working with the internet conncetion on G0/0 and phones connected to any port on the switch.

What I would like to do is connect to the switch from the router and also be able to access the internet from the switch.  I am sure I am routing something wrong but not sure how to figure out what.  Any help is super appreciated.
