So I've set up a small lab in GNS3, and I don't know why I can't ping to my default gateway as I've seem to keep getting destination host unreachable. I've narrowed down the problem to the switch I'm using, because without the switch I know I can ping the default gateway just fine. I can also ping from the router to the Switch just fine. The host is 10.0.4.2/28 with a default gateway of 10.0.4.1 running Windows 10 Education edition, and is on VMnet3. Everything in the diagram is running on VMxnet3.
