Local SA Bindings
Selecting the Local SA Bindings link takes you to the Local SA Bindings page (Figure 6-8). You use this
page to identify valid clients that are able to establish contact with a foreign agent in another network
segment or network other than the client’s home network.

IP Address Range - Start
This field contains the beginning IP address of the range in which client devices must reside in order to
be valid.
IP Address Range - End
This field contains the ending IP address of the range in which the client devices must reside in order be
valid.
Group SPI
This field specifies the security parameter index of the IP address range entered in the IP Address Range
- Start and End fields. The SPI is a 32-bit number (8 hexadecimal digits) assigned to the initiator of the
security association request by the receiving IPSec endpoint. On receiving a packet, the destination
address, protocol, and SPI are used to determine the security association. The security association allows
the node to authenticate or decrypt the packet according to the security policy configured for that
security association.
Group Key
This field contains an authentication key, similar to a WEP key, that the group specified in the security
association uses to access a foreign agent. The group key is a 128-bit key entered as 32 hexadecimal
digits (0-9, a-f, or A-F).
