Section 3 - Configuration

Remote SPI: Remote SPI will be included in the inbound packet transmitted from WAN side of remote gateway. It will be used to de-hash the coming packet and check its integrity. The value of remote SPI should be set in hex format.

Encryption Algorithm: Twoalgorithmscanbeselected:3DES and DES. When the encapsulation protocol is set to AH, the encryption algorithm is unnecessary.

Encryption Key: The encryption key is used by the encryption algorithm. Its length is 8 bytes if encryption algorithm is DES or 24 bytes if 3DES. The key value should be set in hex format.

Authentication Algorithm: Two algorithms can be selected: SHA1 and MD5. But “None” also can

be selected here for non-hashing operation.

Authentication Key: This authentication key is used by the authentication algorithm. Its length is 16 bytes if authentication algorithm is MD5 or 20 bytes if SHA1. Its length will be 0 if no authentication algorithm is chosen. The key value should be set in hex format.
