Unable to ping internet from lab switch connected to PC

[kermit4ip]

Hello everyone. In the interest of full disclosure, I've also posted this in other online communities but haven't found a solution yet. For starters, I'm a Cisco noob, comparatively speaking to others here. I'm trying to get more familiar with IOS and have started acquiring some test lab equipment at home. I have a Catalyst 3560 now and plan to add a couple more older devices to play with. 

One thing I'm trying to figure out is why I can't ping IP addresses on the internet from the 3560. It's directly connected to a PC (192.168.50.121) through its gig interface. I can ping the PC from the switch but can't ping the PC's gateway (192.168.50.1) or anything beyond it on the internet. 

I'm not sure if it's relevant, but the PC has two network interfaces. One of them (192.168.50.121) is the one connected to the 3560, and the other one (192.168.50.41) is connected to an ethernet port on my primary internet router (192.168.50.1), which is a Ubiquiti Edgerouter X. Everything is on the same subnet, but the PC is only thing directly connected to a port on the 3560. 

Is there something I need to do with IP routing to allow the switch to see the Edgerouter? What am I missing? 

Here's the config on the switch:

I imagine it's something obvious, but for the life of me I'm not seeing it. Thank you.

Hello

First of all your pc having its 2 network cards in the same network should not be possible i am assuming that are in different subnets 

with the one of them having a default gateway of the router lan facing interface 

also for the a non public routable network such as the one you have shown to access the internet you would  require the router to perform NAT as the switch won’t be able to do this.

Hi Paul, 

The 2nd adapter in the PC was in the same subnet and was statically assigned. The switch wasn't connected to any router at all, only directly to the PC through that 2nd network card. 

My test lab is on the other side of the house from the one-and-only router I own, which is that Edgerouter. Is there a way to use the PC as a router to reroute traffic from the switch bound for the internet through the PC's primary network card (the one going back to the router)?

Hi kermit4ip,

Could you please try to access it now.
