Manual Key Management
.
Manual Key Management Dialog Box
Once you have created a VPN port, you may access the Manual Key Manage-
ment Dialog Box by clicking on the port’s icon and selecting Manual Key 
Management.
This dialog box sets encryption parameters for non-IKE tunnels. 
Enable Authentication
This checkbox controls whether all tunnel traffic will be authenticated. 
If checked, then each packet will be digitally signed before sending. The 
receiving end of the tunnel will check the signature before allowing the 
traffic onto its local network.
Authentication Method
If Authentication has been enabled, MD5 will appear here and 
packet-by-packet authentication will be done using the Authentication 
Secret
 set below.
Authentication Secret
This secret is used to generate session keys which are used to authenticate 
each packet received from or sent through the tunnel. The secret can be from 
1 to 255 characters in length.
