Emulators Firmware Version. You can close the main window but it is not possible to close the floating window. All Cisco VPN Concentrators ship with the most current code, but users can check the downloads Support contract required to see if more current software is available.
When you find it, select the Upload tab. The "k9" designation for the image name has replaced the originally used 3DES designation for example, vpn Thus, the "k9" now signifies that this is a 3DES image. Data compression increases the memory requirement and CPU utilization for each user session and consequently decreases the overall throughput of the VPN Concentrator.
For this reason, Cisco recommends that you enable data compression only if every member of the group is a remote user that connects with a modem. If any member of the group connects through broadband, do not enable data compression for the group. Instead, divide the group into two groups, one for modem users and the other for broadband users. Enable data compression only for the group of modem users. Use the same name, or different, and open the file in order to view the passwords. You cannot use load balancing with VRRP.
In a load balancing configuration, there are no idle devices. This concept is known as "split tunneling. For additional security, this feature is controllable by the administrator of the VPN Concentrator and not the user. Split tunneling allows you to have the convenience of browsing the Internet while connected through the VPN tunnel. However, it does pose us some risk if the VPN user connected to the corporate network is vulnerable to attacks. It is recommended that the users use a personal firewall in that case.
The release notes for any given VPN Client version discuss interoperability with personal firewalls. Load is calculated as a percentage derived from the active connections divided by the maximum configured connections. The director always tries to have the least load because it is burdened with the additional inherent load of maintaining all of the administrative LAN-to-LAN sessions, calculating all other cluster member loading, and it is responsible for all client redirects.
For a newly configured functional cluster, the director has about a 1 percent load before any connections have been established.
Therefore, the director redirects connections to the backup concentrator until the percentage of load on the backup is higher than the percentage of load on the director. For example, given two VPN Concentrators in "idle" states, the director has a 1 percent load. The secondary is given 30 connections 2 percent load before the director accepts connections.
The VPN Monitor can track 20 headend devices. In a hub-and-spoke scenario, connections from remote sites are monitored at the headend. There is no need to monitor all the remote sites and users since that information can be traced on the hub router. These headend devices can support up to 20, remote users or 2, remote sites. A dual-homed VPN device that goes out to the spoke sites counts as two of the 20 maximum devices that can be monitored.
