5. Firewall, Failover and OOB Access

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 set up a ﬁrewall rule:

• Navigate to the System: Firewall page and click on the Firewall Rules tab.

Note: Prior to ﬁrmware version 3.4, this tab was labeled Port Rules and fewer ﬁrewall rules could be conﬁgured.

• Click New Firewall Rule.

• Fill in the following ﬁelds:

Name Name the rule. This name should describe the ﬁrewall rule policy being implemented (e.g., block

ftp, Allow Tony).

Interface Select the interface the ﬁrewall rule will be applied to (i.e. Any, Dial-Out/Cellular, VPN, Network

Interface, Dial-in etc).

Port Range Specify the Port or range of Ports (e.g. 1000 – 1500) the rule will apply to. This may be left blank.

Source MAC Address Specify the source MAC address to be matched. This may be left blank. MAC addresses use the

format XX:XX:XX:XX:XX:XX, where XX are hex digits.

Source Address Range Specify the source IP address (or address range) to match. IP address ranges use the format ip/

netmask (where netmask is in bits 1-32). This may be left blank.

Destination Range Specify the destination IP address/range to match. IP address ranges use the format ip/netmask

(where netmask is in bits 1-32). This may be left blank.
