Advanced Virtual Private Networking

Digital certificates are strings generated using encryption and authentication schemes that cannot 
be duplicated by anyone without access to the different values used in the production of the string. 
They are issued by Certification Authorities (CAs) to authenticate a person or a workstation 
uniquely. The CAs are authorized to issue these certificates by Policy Certification Authorities 
(PCAs), who are in turn certified by the Internet Policy Registration Authority (IPRA). The 
FVS318v3 is able to use certificates to authenticate users at the end points during the IKE key 
exchange process.

The certificates can be obtained from a certificate server that an organization might maintain 
internally or from the established public CAs. The certificates are produced by providing the 
particulars of the user being identified to the CA. The information provided may include the user's 
name, e-mail ID, and domain name.

policy. 

Authentication Algorithm

If you enable authentication, then use this menu to select the algorithm: 
• MD5 — the default
• SHA1 — more secure

Key - In

Enter the key. 
• For MD5, the key should be 16 characters. 
• For SHA-1, the key should be 20 characters. 
Any value is acceptable, provided the remote VPN endpoint has the same 
value in its Authentication Algorithm Key - Out field.

Key - Out

Enter the key in the fields provided.
• For MD5, the key should be 16 characters. 
• For SHA-1, the key should be 20 characters. 
Any value is acceptable, provided the remote VPN endpoint has the same 
value in its Authentication Algorithm Key - In field.

Check this if you wish NETBIOS traffic to be forwarded over the VPN 
tunnel. The NETBIOS protocol is used by Microsoft Networking for such 
features as Network Neighborhood.
