23. Set the following session parameters:
Name
IP Address
IP
Local Session ID
MTU
Remote Session ID
Define a 31 character maximum name of this tunnel session. After a successful tunnel
connection and establishment, the session is created. Each session name represents a
single data stream.
Specify the IP address used to be as tunnel source ip address. If not specified, the tunnel
source IP address is selected automatically based on the tunnel peer IP address. This
address is applicable only for initiating the tunnel. When responding to incoming tunnel
create requests, it would use the IP address on which it had received the tunnel create
request.
Set the IP address of an L2TP tunnel peer. This is the peer allowed to establish the tunnel.
Set the numeric identifier for the tunnel session. This is the pseudowire ID for the session.
This pseudowire ID is sent in session establishment message to the L2TP peer.
Define the session maximum transmission unit (MTU) as the size (in bytes) of the largest
protocol data unit the layer can pass between tunnel peers in this session. A larger MTU
means processing fewer packets for the same amount of data.
Use the spinner control to set the remote session ID passed in the establishment of the
tunnel session. Assign an ID from 1 - 4,294,967,295.
