Setting up a firewall in your GENI topology is as simple as dragging a node onto the experiment pane. Simply filter your list of resource types using the dropdown menu on the left. Select ‘firewall’:


And drag it onto your experiment:


You can network and configure the properties of a firewall just like you can with any other resource type. It’s just another node in the topology:


In the properties window above, you can specify that the firewall is either open, closed, or basic.

  • Open: All traffic may flow freely
  • Closed: No traffic may flow
  • Basic: SSH and HTTP/HTTPs are allowed

Using an “open” style, you will be able to access the node to define rules at a later time.
