Section 3 - Configuration

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.

Two algorithms can be selected: 3DES

and DES. When the encapsulation

protocol is set to AH, the encryption

algorithm is unnecessary.

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.

Two algorithms can be selected:

SHA1 and MD5. But “None” also can

be selected here for non-hashing operation.

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.
