Configure Protocol Dialog Box
Packet inspection can be configured in zone-based firewall rules by the selection of specific protocol
objects, which define Port Application Mapping (PAM) parameters (Layer 4 protocols and ports, and
optionally specific networks and hosts). A Layer 7 (HTTP, IMAP, Instant Messaging, and peer-to-peer)
protocol can also include a deep-packet inspection policy specific to that protocol. Refer to Adding and
Editing Zone-based Firewall Rules, page 21-59 for information about selecting protocols during
zone-based firewall rule definition.
The Configure Protocol dialog box is used to edit existing protocol definitions, and to create custom
definitions, for use with zone-based firewall rules. For example, if a protocol does not use its default
ports for some or all networks, you can configure different port mappings.
Navigation Path
The Configure Protocol dialog box is accessed from the Protocol Selector Dialog Box, page 21-64, as
follows:
• Click the Create (+) button below the Selected Protocols list to create a new protocol.
• Select a protocol in the Selected Protocols list, and click the Edit (pencil) button to edit that protocol.
