Figure 27: Connection Security Refresh panel of the Advanced VPN page<br />
At regular intervals, the <strong>Access</strong> <strong>Server</strong> renegotiates a TLS session with a given VPN client. This is<br />
to maintain the security of the TLS connection. The refresh interval is specified as a number of<br />
minutes. 60 minutes is a reasonable default; less than 10 minutes is not recommended.<br />
During the security refresh, the VPN Client user is re-authenticated, however VPN Clients may<br />
cache the user's credentials and make this re-authentication go unnoticed by the user.<br />
4.2.5.6 Windows Networking<br />
Figure 28: Windows Networking panel of the Advanced VPN page<br />
To allow Windows VPN clients to convert NetBIOS host names into IP addresses, you can<br />
configure the IP address of a primary (and optionally, a secondary) WINS server. You can also<br />
specify the Node type for the NetBIOS over TCP/IP communication. Additionally, you can specify<br />
the IP address of a NBDD (NetBIOS over TCP/IP Datagram Distribution server).<br />
Optionally, the NetBIOS over TCP/IP Scope ID can be specified as a character string (which is<br />
appended to a NetBIOS name). The use of NetBIOS Scope IDs allow computers to use the same<br />
(NetBIOS) computer name, as long as have different Scope IDs.<br />
