DESCRIPTION
This is the security index number.
This field displays the identification name for this VPN policy. This name is unique for
each connection where the secure gateway IP address is a public static IP address.
When the secure gateway IP address is 0.0.0.0 (as discussed in the last chapter), there
may be different connections using this same VPN rule. In this case, the name is followed
by the remote IP address as configured in Menu 27.1.1. – IPSec Setup. Individual
connections using the same VPN rule may be terminated without affecting other
connections using the same rule.
This field displays Tunnel mode or Transport mode. See previous for discussion.
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. Encryption
methods include 56-bit DES and 168-bit 3DES. NULL denotes a tunnel without
encryption.
An incoming SA may have an AH in addition to ESP. The 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 Prestige processing requirements and communications
latency (delay).
Press [SPACE BAR] to choose from Refresh, Disconnect, None, Next Page, or
Previous Page and then press [ENTER]. You must select a connection in the next field
when you choose the Disconnect command. Refresh displays current active VPN
connections. None allows you to jump to the "Press ENTER to Confirm..." prompt.
Select Next Page or Previous Page to view the next or previous page of rules
(respectively).
Type the VPN connection index number that you want to disconnect and then press
[ENTER].
