Source Address: This allows the user to restrict access to a port forward to a specific address. In
most cases, this should be left blank
Input Port Range: The range of ports to forward to the destination IP. These will be the port(s)
specified when accessing the port forward. These ports need not be the same as
the output port range.
Protocol: The protocol of the data being forwarded. The options are TCP or UDP
Output Address: The target of the port forward. This is an address on the internal network
where packets sent to the Input Interface on the input port range are sent.
Output Port Range: The port or ports that the packets will be redirected to on the Output
Address.
For example, to forward port 8443 to an internal HTTPS server on 192.168.10.2, the following settings
would be used:
Input Interface: Any
Input Port Range: 8443
Protocol: TCP
Output Address: 192.168.10.2
Output Port Range: 443
5.8.4 Firewall rules
Firewall rules can be used to block or allow traffic through an interface based on port number, the
source and/or destination IP address (range), the direction (ingress or egress) and the protocol. This can
be used to allow custom on-box services, or block traffic based on policy.
To setup a firewall rule:
Navigate to the System: Firewall page, and click on the Firewall Rules tab
