Good evening,
I recently encountered an issue with my project here. From a given computer on a router I cannot ping another computer on a different router. For example, I cannot ping a computer from the Berlin router with a computer from the DC router. Each time I ping from PC1, it results in either a "request timed out" or "a destination unreachable". Is there any oversight in configuring the routers or switches? I have a copy of the .pkt file for my project.
