Host Unable to Ping Outside of LAN

[alexbarrycooper]

Hello, I'm currently having an issue with being able to ping the IP address 8.8.8.8 with my host computer. I am using a 3550 Cisco switch and a 2621xm Cisco router with the Host computer connected to the switch along my router's 0/1 interface connected to the switch my router's 0/0 interface connected into my ISPs modem and the modem is connected to the internet.

Do you have the vlans created on the switch

Hello

So its looks like you have L2/l3 connectivity so  check the cabling

The rtr fa0/1 needs to be in a up/up state for you lan users to be able to reach internet.

It Works!

Embarrassing, but I had the cable from the router plugged into the wrong vlan (vlan 0005). After fixing that everything started to work.

Thank you, for all the information that you gave me on my network and some of its flaws. Also thank you for your patience and time!

I think he meant

"remove the static completely and then post"

and not

"remote the static completely and then post"

[paul driver]

Hello

First thoughts is NAT not being enabled and./or missing default route, its hard to figure out, Are you able to post the configuration of the router and switch?
