I have a lab with different networks and on one network I have a layer 2 and layer 3 switch, the layer 3 switch is connected to a router. I have a few different vlans on this network. All vlans can communicate with each other and the switches and router.
I can ping externally to another client on another network form the layer 3 switch with no problem. However, I cannot ping from the layer 2 switch or computers on the vlans on the same network to these external hosts. What is it that is preventing replies when I ping externally?
There are no acl's on the routers.
