Getting internet to work from switch

jpanzica747

Level 1

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.

Hello,

 

make the changes marked in bold. When you are done, post the full configurations of the switch and the router so we can double check everything:

 

Switch

I think this fixed it and it is working correctly.  Thank you for your help it is very appreciated.
