|
Port Number
|
The port number that you want to use for SSL VPN sessions. The default port is 443, for HTTPS traffic; the range is 1024 through 65535. If you change the port number, All current SSL VPN connections terminate, and current users must reconnect.
Note If HTTP port redirection is enabled, the default HTTP port number is 80.
Enter the name of a port list, or click Select to open the Port List Selector from which you can make your selection, or create a port list object. A port list object is a named definition of one or more port ranges that you use when defining service objects.
|
Default Idle Timeout
|
Amount of time, in seconds, that an SSL VPN session can be idle before the security appliance terminates it.
This value applies only if the Idle Timeout value in the group policy for the user is set to zero (0), which means there is no timeout value; otherwise the group policy Idle Timeout value takes precedence over the timeout you configure here. The minimum value you can enter is 1 minute. The default is 30 minutes (1800 seconds). Maximum is 24 hours (86400 seconds).
We recommend that you set this attribute to a short time period. This is because a browser set to disable cookies (or one that prompts for cookies and then denies them) can result in a user not connecting but nevertheless appearing in the sessions database. If the Simultaneous Logins attribute for the group policy is set to one, the user cannot log back in because the database indicates that the maximum number of connections already exists. Setting a low idle timeout removes such phantom sessions quickly, and lets a user log in again.
|
Max Session Limit
|
The maximum number of SSL VPN sessions you want to allow.
Be aware that the different ASA models support SSL VPN sessions as follows: ASA 5510 supports a maximum of 150; ASA 5520 maximum is 750; ASA 5540 maximum is 2500.

|
When selected, enables you to override the "account-disabled" indicator from an AAA server. This configuration is valid for servers, such as RADIUS with NT LDAP, and Kerberos, that return an "account-disabled" indication.
Note If you are using an LDAP directory server for authentication, password management is supported with the Sun Microsystems JAVA System Directory Server (formerly named the Sun ONE Directory Server) and the Microsoft Active Directory.
Sun—The DN configured on the security appliance to access a Sun directory server must be able to access the default password policy on that server. We recommend using the directory administrator, or a user with directory administrator privileges, as the DN. Alternatively, you can place an ACI on the default password policy.
Microsoft—You must configure LDAP over SSL to enable password management with Microsoft Active Directory.
|
Enable Notification Upon Password Expiration to Allow User to Change Password
|
When selected, enables the security appliance to notify the remote user at login that the current password is about to expire or has expired, then offers the user the opportunity to change the password.

|
Enable Notification Prior to Expiration
|
Available only if you selected the Enable Notification Upon Password Expiration to Allow User to Change Password check box.
When selected, enables you to specify the number of days before expiration to warn the user about the pending expiration.
If the current password has not yet expired, the user can still log in using that password. This parameter is valid for AAA servers that support such notification—RADIUS, RADIUS with an NT server, and LDAP servers. The security appliance ignores this command if RADIUS or LDAP authentication has not been configured.
Note The selection of this check box just enables the notification. You must specify the number of days for it to take effect.
|
Notify Prior to Expiration

WINS Servers List
|
The name of the WINS (Windows Internet Naming Server) servers list to use for CIFS name resolution.
SSL VPN uses the CIFS protocol to access or share files on remote systems. When you attempt a file-sharing connection to a Windows computer by using its computer name, the file server you specify corresponds to a specific WINS server name that identifies a resource on the network.
A WINS servers list defines a list of WINS servers, which are used to translate Windows file server names to IP addresses. The security appliance queries the WINS servers to map WINS names to IP addresses. You must configure at least one, and up to three WINS servers for redundancy. The security appliance uses the first server on the list for WINS/CIFS name resolution. If the query fails, it uses the next server.
WINS server lists are predefined objects. If you want to use a different WINS servers list, click Select to open the WINS Server List Selector dialog box that lists all available WINS Servers list objects, and in which you can create WINS Servers list objects.

Enable
|
When selected, enables the use of cache settings for the security appliance. This check box is selected by default.
When deselected, the cache settings configured on the security appliance do not take effect and all the fields under the Performance tab are grayed out.
|
Maximum Object Size
|
The maximum size (in kilobytes) of an HTTP object that can be stored in the cache on the security appliance.
The maximum size limit for an HTTP object is 10,000 kilobytes. The default is 1000 Kb.
|
Minimum Object Size
|
The minimum size of an HTTP object that can be stored in the cache (in kilobytes) on the security appliance.
The minimum size range is 0-10,000 Kb. The default is 0 Kb.
|
Last Modified Factor
|
Specifies an integer to set a revalidation policy for caching objects that have only the last-modified timestamp, and no other server-set expiration values. The range is 1-100. The default is 20.
The Expires response from the origin web server to the security appliance request, which indicates the time that the response expires, also affects caching. This response header indicates the time that the response becomes stale and should not be sent to the client without an up-to-date check (using a conditional GET operation).
The security appliance can also calculate an expiration time for each web object before it is written to disk. The algorithm to calculate an object's cache expiration date is as follows:
Expiration date = (Today's date - Object's last modified date) * Freshness factor
After the expiration date has passed, the object is considered stale and subsequent requests causes a fresh retrieval of the content by the security appliance. Setting the last modified factor to zero is equivalent to forcing an immediate revalidation, while setting it to 100 results in the longest allowable time until revalidation.
|
Expiration Time
|
The amount of time (in minutes) that the security appliance caches objects without revalidating them. The range is 0-900 minutes. The default is one minute.
Revalidation consists of rejecting the objects from the origin server before serving the requested content to the client browser when the age of the cached object has exceeded its freshness lifetime. The age of a cached object is the time that the object has been stored in the security appliance's cache without the security appliance explicitly contacting the origin server to check if the object is still fresh.
|
Cache Compressed Content
|
When selected, enables compressed objects (zip, gz, and tar files) for SSL VPN sessions to be cached on the security appliance.
When you deselect this check box, the security appliance stores objects before it compresses them.
|
Cache Static Content
|
When selected, enables static content to be cached on the security appliance.
Each web page comprises static and dynamic objects. The security appliance caches individual static objects, such as image files (*.gif, *.jpeg), java applets (.js), and cascading style sheets (*.css), etc.
