Virtual Private Networks (VPNs) 12-11 You can remove a Filter Set. You can choose to configure Advanced IP Profile Options (see “Advanced IP Profile Options,” in thefollowing section).Note: The SPI title field above changes to SPI (Security Parameters Index) -- Use Advanced IP Profile Optionsif any of the SPI values differ from each other.Advanced IP Profile Options You can specify an ESP Receive SPI. The value must be unique over the set of all ESP SPIs specified forthe remote tunnel endpoint. You can specify an ESP Transmit SPI. The value must be unique over the set of all ESP SPIs specified forthe remote tunnel endpoint. You can specify an AH Receive SPI if AH authentication has been requested. The value must be uniqueover the set of all AH SPIs specified for the router. You can specify an AH Transmit SPI if AH authentication has been requested. The value must be uniqueover the set of all AH SPIs specified for the remote tunnel endpoint. You can specify a Local Tunnel Endpoint Address. If not 0.0.0.0, this value must be one of the assignedinterface addresses, either WAN or LAN. This is used as the source address of all IPsec traffic. You can specify a Next Hop Gateway. If you specify the Remote Tunnel Endpoint Address, and the addressis in the same subnet as the Remote Members Network you specified in the IP Profile Parameters, theNext Hop Gateway option allows you to enter the address by which the gateway partner is reached.If you do not specify the Remote Tunnel Endpoint Address, the router will use the default gateway to reachthe partner. If the partner should be reached via an alternate port (for example, the LAN instead of theWAN), the Next Hop Gateway field allows this path to be resolved.Advanced IP Profile OptionsESP Receive SPI: 123456789ESP Transmit SPI: 123456789AH Receive SPI: 123456789AH Transmit SPI: 123456789Local Tunnel Endpoint Address: 0.0.0.0Next Hop Gateway: 0.0.0.0
