This field displays Tunnel mode or Transport mode. See earlier for a discussion of
these. You need to finish configuring the VPN policy in menu 27.1.1.1 or 27.1.1.2 if ???

IPSec
Algorithm
Algorithm
This field displays the security protocols used for an SA. ESP provides confidentiality
and integrity of data by encrypting the data and encapsulating it into IP packets. Encryp-
tion methods include 56-bit DES and 168-bit 3DES. NULL denotes a tunnel without
encryption.
AH (Authentication Header) provides strong integrity and authentication by adding
authentication information to IP packets. This authentication information is calculated
using header and payload data in the IP packet. This provides an additional level of
security. AH choices are MD5 (default - 128 bits) and SHA -1(160 bits).
Both AH and ESP increase the Prestige’s processing requirements and communica-
tions latency (delay).

When the Addr Type field in Menu 27.1.1 IPSec Setup is configured to Single, this is a
static IP address on the network behind the remote IPSec router.
