IPsec Protocols (Manual Keys) page
Encapsulation Type
Specify how the selected IPsec protocols (ESP or AH) are encapsulated:

Transport (default): Only the user data in each IP packet is protected, the IP packet header is not protected.

Tunnel: All packet fields are protected, including the IP packet header.
Cryptographic Parameters
Set the encryption method/strength and the authentication methods used:

ESP IPsec encapsulating security payload (ESP) protocol for IP packets. ESP headers are inserted in packets to ensure privacy and integrity of packet contents. Select among the supported encryption methods/strengths and authentication methods to be used for data protection.

AH IPsec authentication header (AH) protocol for IP packets. AH headers are inserted in packets to protect integrity of packet contents through cryptographic checksums. Select among the supported authentication methods.
HP Jetdirect Print Servers caution IPsec Protocols (Manual Keys) CAUTION:

IPsec AH might not function properly in environments that use network address translation (NAT).

HP Jetdirect Print Servers note IPsec Protocols (Manual Keys) NOTE:

For manual keys, you can select only one authentication method. You cannot use ESP authentication if AH is enabled. If you enable ESP and AH, you must select an AH authentication method.
