 For Stateful Mode configuration, chain modules marked with 2 will not apply. Stateful Mode configuration is a feature that allows administrators to define how packets are processed by different firewall kernel modules in inbound and outbound directions. Chain modules are firewall kernel modules that perform various security functions, such as VPN, IPS, QoS, etc. Each chain module is associated with a key, which specifies the type of traffic applicable to the chain module. The key can be one of the following values: 0 for all packets, 1 for stateful packets, 2 for stateless packets, and 3 for no match packets. For Stateful Mode configuration, only chain modules with key 0 or 1 will apply, as they handle all packets or stateful packets. Chain modules with key 2 will not apply, as they handle stateless packets, which are not relevant for Stateful Mode configuration.

A star community is a VPN topology where one or more satellites connect to a center gateway. The center gateway can be a Security Gateway or a Security Management Server. The VPN routing option determines how the traffic is routed between the satellites and the center, and between the satellites themselves. There are three VPN routing options available in a star community12:

• To center only: The satellites can only communicate with the center gateway, and not with each other or with any other VPN targets. This option is useful for remote access clients that only need to access resources on the center gateway.
• To center, or through the center to other satellites, to Internet and other VPN targets: The satellites can communicate with the center gateway, and also with other satellites, Internet hosts, and other VPN targets through the center gateway. This option is useful for branch offices that need to access resources on the center gateway, as well as on other branch offices, Internet hosts, and other VPN targets.
• To center and to other satellites through center: The satellites can communicate with the center gateway, and also with other satellites through the center gateway. However, they cannot communicate with Internet hosts or other VPN targets. This option is useful for branch offices that need to access resources on the center gateway and on other branch offices, but not on Internet hosts or other VPN targets.

Therefore, the options A (To satellites through center only) and D (To center only) are not valid VPN routing options in a star community.

 When SecureXL is enabled, all packets should be accelerated, except packets that match the following conditions: CIFS packets. SecureXL is a technology that accelerates network traffic processing by offloading intensive operations from the Firewall kernel to a dedicated SecureXL device. However, some packets cannot be accelerated by SecureXL due to various reasons, such as unsupported features, security policy settings, or protocol limitations. One example of packets that cannot be accelerated by SecureXL are CIFS packets, which are used for file sharing and access over SMB protocol. CIFS packets are not accelerated by SecureXL because they require stateful inspection by the Firewall kernel.
