You can use a previously created IP, MAC or port list. Select a combination of IP and MAC addresses, and if available for the frame type, Port and Specific Flags for the Packet Source and Packet Destination. Select a Packet Source and Packet Destination If you select "Other" as the protocol, you also need to enter a protocol number. If you select the Internet Protocol (IP) frame type, you need to select the transport Protocol. Note that the Virtual Appliance does not have these restrictions and can examine all frame types, regardless of the operating system of the virtual machine it is protecting. Packets with other frame types will be allowed through. On Solaris, Deep Security Agents will only examine packets with an IP frame type, and Linux Agents will only examine packets with IP or ARP frame types. The rule can allow traffic (it will exclusively allow traffic defined by this rule.).The rule can deny traffic (it will deny traffic defined by this rule.).The rule can force allow defined traffic (it will allow traffic defined by this rule without excluding any other traffic.).This action will make entries in the logs but will not process traffic.

If the protocol is TCP or UDP and the traffic direction is "outgoing", the source ports must be one or more specified ports (Not "Any"), and the destination ports must be "Any".

If the protocol is TCP or UDP and the traffic direction is "incoming", the destination ports must be one or more specified ports (not "Any"), and the source ports must be "Any".

Source and Destination IP and MAC: all "Any".

Protocol: TCP, UDP, or other IP protocol.
