The advantage for SSL VPN comes from accessibility from almost any Internet-connected system without the need to install additional desktop software. Permanent licenses—No usage period is associated with these licenses. All permanent licenses are node locked and validated during installation and usage. Evaluation licenses—These are metered licenses that are valid for a limited period.
The usage period of a license is based on a system clock. The evaluation licenses are built into the image and are not node locked. The evaluation licenses are used only when there are no permanent, extension or grace period licenses available for a feature. An end-user license agreement EULA has to be accepted before using an evaluation license.
Extension licenses—Extension licenses are node-locked metered licenses. These licenses are installed using the management interfaces on the device. A EULA has to be accepted as part of installation. Grace-rehost licenses—Grace period licenses are node locked metered licenses. These licenses are installed on the device as part of the rehost operation. A EULA has to be accepted as a part of the rehost operation. For all the license types, except the evaluation license, a EULA has to be accepted during the license installation.
This means that all the license types except the evaluation license are activated after installation. On a successful user validation, a request is made to the licensing module to get a seat. When multiple policies and profiles are configured, the total number of sessions are equal to the total sessions allowed by the license.
A seat count is released when a session is deleted. A session is deleted because of reasons such as log out by the user, session idle timeout or Dead Peer Detection DPD failure. Rarely a few sessions which do not have active connections may appear to be consuming licenses. This typically denotes that this is a transition state and the session will get expired soon. The same user can create multiple sessions and for each session a seat count is reserved.
The seat reservation does not happen in the following cases:. Full-tunnel session creation from a browser session. Full-tunnel session is up and a crypto rekey is done. When the total active sessions are equal to the maximum license count of the current active license, no more new sessions are allowed.
The reserved seat count or session is released when the following occurs:. You can use the show webvpn license command to display the available count and the current usage.
To display the current license type and time period left in case of a nonpermanent license, use the show license command. To get information related to license operations, events, and errors, use the debug webvpn license command. Therefore the old licenses become inactive when a new license is applied. For example, when you are upgrading your license from 10 counts to 20 counts an increase of 10 counts on the current 10 counts , Cisco provides a single 20 count license.
The old license for 10 counts is not required when a permanent license for a higher count is available. However, the old license will exist in an inactive state as there is no reliable method to clear the old license. A license count is associated with each license, and the count indicates the instances of the feature available for use in the system.
For migrating from any Cisco IOS End-user login and authentication is performed by the web browser to a secure gateway using an HTTP request. This process creates a session that is referenced by a cookie. All requests sent by the browser include the authentication cookie.
The portal page provides all the resources available on the internal networks. For example, the portal page could provide a link to allow the remote user to download and install a thin-client Java applet for TCP port forwarding or a tunneling client. In a clientless mode, the remote user accesses the internal or corporate network using the web browser on the client machine. Linux requires that the Samba application is installed before CIFS file shares can be remotely accessed.
Thin-client mode, also called TCP port forwarding, assumes that the client application uses TCP to connect to a well-known server and port. The Java applet acts as a TCP proxy on the client machine for the services that you configure on the gateway. A Java applet is loaded through the browser that verifies the JRE version. The Java applet will refuse to run if a compatible JRE version is not detected. You cannot use thin-client mode for applications such as FTP, where the ports are negotiated dynamically.
You can use TCP port forwarding only with static ports. There is a known compatibility issue with the encryption type and Java. If the Java port-forwarding applet does not download properly and the configuration line ssl encryption 3des-sha1 aes-sha1 is present, you should remove the line from the WebVPN gateway subconfiguration. If HTTP proxy is enabled, the Java applet acts as the proxy for the browser of the user, thereby connecting the client workstation with the gateway.
The home page of the user as defined by the user group is opened automatically or, if configured by the administrator, the user is directed to a new website. Remote users can use their own bookmarks, and there is no limit on cookies. Because there is no mangling involved and the client can cache the objects, performance is much improved over previous options for configuring the HTTP proxy and portal page.
Applet examines the registry to determine the exchange and local catalog server and create server entries that refer to those servers. Applet opens a connection to the secure gateway and delivers the requests from Outlook. Data flows from Outlook, through the applet and the secure gateway, to the exchange server. User closes the applet. Before closing, the applet undoes configuration Steps 3 and 4. Applet updates the proxy configuration of the browser to be the local loopback address with an available local port by default, port Applet, if so configured, opens the home page of the user, or the user browses to a new website.
Applet opens a connection to the secure gateway and delivers the requests from the browser. Data flows from the browser, through the applet and the secure gateway, to the web server. In a typical clientless remote access scenario, remote users establish an SSL tunnel to move data to and from the internal networks at the application layer for example, web and e-mail.
Therefore, tunnel mode supports most IP-based applications. The tunnel connection is determined by the group policy configuration.
Users provide their usernames and passwords via the gateway page URL and do not have to reenter their usernames and passwords from the login page. Authorization is enhanced to support more generic authorization, including local authorization.
Certificate-only authorization requires the user to provide a authentication, authorization, and accounting AAA authentication certificate as part of the WebVPN request, but does not require the username and password for authorization. To configure certificate-only authorization use the authentication certificate command.
Users also need to configure public key infrastructure PKI AAA authorization using the entire subject name to retrieve the user name from the subject name in the certificate and use it for authorization. As a result, a unique username is required for each user. Users can use the debug crypto pki transactions command to see which username is being used by the device.
The WebVPN gateway then presents the login page to the user. The AAA authentication list and the AAA authorization lists configured on the server are then used for authentication and authorization.
To configure two-factor authentication and authorization mode use the authentication certificate aaa command. If the username-prefill command is configured, the username textbox on the login page will be disabled. The user will be asked only for their password on the login page. When the user does not provide the WebVPN context, the identification of the WebVPN context at runtime is possible using certificate map matching by matching the certificate presented by the client with the certificate map match rules.
To configure certificate map matching in WebVPN use the match-certificate command. Cisco AnyConnect client has certificate match functionality allowing it to select a suitable certificate while initiating tunnel connection with SSL VPN. In the case of standalone mode, the certificate selection is made based on the certificate match. When selecting a certificate, Cisco AnyConnect client can select the appropriate certificate based on the AnyConnect client profile attributes. The profile file is imported after modification by the administrator using the svc profile command.
The following are the certificate match types available with Cisco AnyConnect client:. Certificate key usage matching offers a set of constraints based on the broad types of operations that can be performed with a given certificate. This matching allows an administrator to limit the certificates that can be used by the client based on the Extended Key Usage fields.
This certificate matching capability allows an administrator to limit the certificates that can be used by the client to those matching the specified criteria and criteria match conditions. This includes the ability to specify that a certificate must or must not have a specified string and also if wild carding for the string should be allowed.
The ability to install AnyConnect in a standalone mode is also added. In addition, the Release You can ignore these errors as the client is able to connect and send or receive data traffic successfully. The Automatic Applet Download feature must be configured on a group policy basis. Users still have to allow the Java applet to be downloaded. The dialog box appears, asking for permission. This feature adds the following new AAA attributes:.
This placement reduces the vulnerability of the router by separating the Internet routes or the global routing table. The backend, or IVRF, functionality remains the same. This feature is enabled by default. To turn off full-tunnel Cisco Express Forwarding support, use the no webvpn cef command. To take full advantage of Cisco Express Forwarding support, the hardware crypto engine is required.
This method helps improve the WebVPN throughput performance. The improved customization of the user interface provides for greater flexibility and the ability to tailor portal pages for individualized views. Enhancements are made to the following web screens:.
The figure below is an example of a typical login screen. The banner is a small popup box that appears before the portal page displays and after a user is logged in. The message in the popup box is configured using the banner command. Login screens can be customized by an administrator. The following figure shows the fields that can be customized. You can customize this page to contain the following:.
The Bookmark links are listed under the Personal folder, and the server links are listed under Network File in the figure below. URL entry box may be present or can be hidden using the hide-url-bar command. E-mail access is supported by thin-client mode, which is downloaded using the Thin Client link. Time to redirect to the home page is displayed on the WebVPN portal page if you have configured the home page redirect time using the webvpn-homepage command.
Portal pages can be customized by an administrator. The following figure shows various fields, including the fields that can be customized by an administrator. The fields that can be customized by an administrator are as follows:. The table below provides information about various fields on the portal page. When a user selects this icon, a dialog box is added so that a new bookmark can be added to the Personal folder. The route-target is for customer-spoke connectivity.
