Mapping Certificates to IPsec or SSL VPN Connection Profiles
• Client VPN Software Update Table—Lists the client type, VPN Client revisions, and image URL
for each client VPN software package installed. For each client type, you can specify the acceptable
client software revisions and the URL or IP address from which to download software upgrades, if
necessary. The client update mechanism (described in detail under the Client Update dialog box)
uses this information to determine whether the software each VPN client is running is at an
appropriate revision level and, if appropriate, to provide a notification message and an update
mechanism to clients that are running outdated software.
–
Client Type—Identifies the VPN client type.
–
VPN Client Revisions—Specifies the acceptable revision level of the VPN client.
–
Image URL—Specifies the URL or IP address from which the correct VPN client software
image can be downloaded. For dialog boxes-based VPN clients, the URL must be of the form
http:// or https://. For ASA 5505 in client mode or VPN 3002 hardware clients, the URL must
be of the form tftp://.
Modes
