In the wizard you have to choose a unique name for your firewall. For each firewall rule, you have to define following fields:

  • Source: The CIDR (Classless Inter-Domain Routing e.g. 192.168.0.0/24) address of the incoming connection. You can also select a firewall rule as a source.
  • Protocol: The protocol of the incoming connection. It can be custom TCP, UDP protocol, or SSH, FTP etc.
  • Port(Service): For protocols like SSH, FTP, the port is automatically selected. You have to provide ports for custom protocols.
