Corrections to Improving NP6 or NP7 GTP performance.

Improvements to GTPv0/v1 message reference and GTPv2 message reference.

Minor changes throughout the document.

Corrected information about how the policy-filter option works when configuring GTPv0/v1 and GTPv2 policy filtering. See Adding GTPv0/v1 policy filters to a GTP profile and Adding GTPv2 policy filters to a GTP profile.

Improved the explanation of how to select source and destination firewall addresses when setting up a GTP IP filter, see Encapsulated IP traffic filtering.

Added more information about SCTP support and creating SCTP firewall policies. See SCTP firewall.

Improvements to the descriptions in the following sections:

• Adding GTPv0/v1 policy filters to a GTP profile.

• Adding GTPv2 policy filters to a GTP profile.

New section: Diagnose firewall gtp tunnel list command.

Updated the list of FortiGate models supported by FortiOS Carrier in FortiOS Carrier licensing to include the FortiGate-4200F, 4201F, 4400F, and 4401F. Added information about the NP7 processor to Improving NP6 or NP7 GTP performance.

Updated the list of FortiGate models that support FortiOS Carrier in FortiOS Carrier licensing.

Added information about supported models to Improving NP6 or NP7 GTP performance.

New section: GTPv2 message reference. Changes to GTPv0/v1 message filtering and GTPv2 message filtering to clarify how FortiOS Carrier handles unknown GTP message types.

Misc changes and two new sections:

• FortiOS Carrier licensing.
• FortiOS Carrier features.
