Shared secret: The shared secret used for authentication of the mobile node at the
home agent. This can be either a 128-bit hexadecimal value or a random length
ASCII string.
Life time: The lifetime of security associations in seconds
UDP encapsulation: Specifies whether UDP encapsulation shall be used or not. To
allow NAT traversal, UDP encapsulation must be enabled.
Mobile network address: Optionally specifies a subnet which should be routed to the
mobile node. This information is forwarded via Network Mobility (NEMO) exten-
sions to the home agent. The home agent can then automatically add IP routes
to the subnet via the mobile node. Note that this feature is not supported by all
third party home agent implementations.
Mobile network mask: The network mask for the optional routed network
If MIP is run as a home agent, you will have to set up a home address and network
mask for the home agent first. Then you will need to add the configuration for all mobile
nodes, which is made up of the following settings:
SPI: The Security Parameter Index (SPI) identifying the security context for the tunnel
between the mobile node and the home agent. This is used to distinguish mobile
nodes from each other. Therefore each mobile node needs to be assigned a unique
