Imagine of Topology, Controller and my terminalsSo im currently trying to setup a simple router that blocks traffic from a specific IP, but allows other connections to travel freely. The picture shows my code from my controller and the other is the topology for my connections. Please help me!!

I am trying to get h1 h2 h3 and h5 to connect with eachother, (see terminal on right side “h1 ping h2”) while also making sure that “h2 ping h4” get blocked.
