Manual Keys Use this page to configure encryption keys and Security Associations manually. Because the applicable hosts will also be manually configured, authentication and dynamic key generation are not needed. Items on this page are described below. Table 5-8 Manual Keys page Item ESP SPI (256 to 4095 ASCII) AH SPI (256 to 4095 ASCII) Description If ESP is enabled on the IPsec Protocols page, the ESP SPI (Security Parameters Index) fields are provided. The ESP SPI is a 32-bit field in an ESP header that helps to identify the IPsec Security Association (SA). in: Enter a value for an SA used for received packets. out: Enter a value for an SA used for transmitted packets from the print server. If AH is enabled on the IPsec Protocols page, the AH Security Parameters Index (SPI) edit fields are provided. An AH SPI is a 32-bit field in an Authentication header that helps to identify the IPsec SA. in: Enter a value for an SA used for received packets. out: Enter a value for an SA used for transmitted packets from the print server. CAUTION The use of IPsec AH may not function properly in environments that use Network Address Translation (NAT). Key Format Encryption Hash Choose whether you will use Hexadecimal values or ASCII characters to specify Encryption or Hash entries. Enter the Encryption keys for packets received (in) or sent (out) by the print server. Enter the Hash keys for packets received (in) or sent (out) by the print server. The Hash keys must be the same for ESP and AH protocols if both are enabled. Summary This page provides summary information for the IPsec rule.
