Configuring Firewall Settings

Start/End Time:

Src IP Address:

Dest IP Address:

Protocol:

Apply Stateful Inspection:

Enable if you configure a Log Tag.

The time range during which this rule is to be in effect, specified in military units.

IP address criteria for the source computer(s) from which the packet originates. Use the following expressions to specify IP:

any: any source IP address

lt: less than

lteq: less than or equal to

gt: greater than

eq: equal to

neq: not equal to

range: within the specified range, inclusive

out of range: outside the specified range

self: the IP address of the router interface on which this rule takes effect.

IP address rule criteria for the destination computer(s), i.e. the IP address of the computer to which the packet is being sent.

In addition to the options described for the “Src IP Address” field, the following option is available:

bcast: Specifies that the rule will be invoked for any packets sent to the broadcast address for the receiving interface. (The broadcast address is used to send packets to all hosts on the LAN or subnet connected to the specified interface). When you select this option, you do not need to specify the address, so the address fields are dimmed.

The basic IP protocol criteria that must be met for a rule to be invoked. Using the options in the drop-down list, you can specify that packets must contain the selected protocol (eq), that they must not contain the specified protocol (neq), or that the rule can be invoked regardless of the protocol (any). TCP, UDP and ICMP are commonly IP protocols; others can be identified by number from 0-255 as defined by IANA.

If this option is enabled, then stateful filtering is performed and the rule is also applied in the other direction on the given interface during an IP session.
