Transparent Mode | Servers receiving packets after WAN optimization “see” different source addresses depending on whether or not you select Transparent Mode. For more information, see “WAN optimization transparent mode”. |
Authentication Group | Select this option and select an authentication group so that the client and server-side FortiGate units must authenticate with each other before starting the WAN optimization tunnel. You must also select an authentication group if you select Secure Tunneling for any protocol. You must add identical authentication groups to both of the FortiGate units that will participate in the WAN optimization tunnel. For more information, see “Configuring authentication groups”. |
Protocol | Select CIFS, FTP, HTTP or MAPI to apply protocol optimization for the selected protocols. See “Protocol optimization”. Select TCP if the WAN optimization tunnel accepts sessions that use more than one protocol or that do not use the CIFS, FTP, HTTP, or MAPI protocol. |
SSL Offloading | Select to apply SSL offloading for HTTPS or other SSL traffic. You can use SSL offloading to offload SSL encryption and decryption from one or more HTTP servers to the FortiGate unit. If you enable this option, you must configure the security policy to accept SSL‑encrypted traffic. If you enable SSL offloading, you must also use the CLI command config wanopt ssl‑server to add an SSL server for each HTTP server that you want to offload SSL encryption/decryption for. For more information, see “Turning on web caching for HTTPS traffic”. |
Secure Tunnelling | The WAN optimization tunnel is encrypted using SSL encryption. You must also add an authentication group to the profile. For more information, see “Secure tunneling”. |
Byte Caching | Select to apply WAN optimization byte caching to the sessions accepted by this rule. For more information, see “Byte caching”. |
Port | Enter a single port number or port number range. Only packets whose destination port number matches this port number or port number range will be optimized. |
