VPN lets users establish a secure, remote access VPN tunnel to a security appliance using a web browser. Users do not need a software or hardware client. Web. VPN provides secure and easy access to a broad range of web resources and web enabled applications from almost any computer on the Internet. They include Internal websites Web enabled applications NTActive Directory file shares E mail proxies, including POP3. S, IMAP4. S, and SMTPS MS Outlook Web Access MAPI Application Access that is, port forwarding for access to other TCP based applications Web. VPN uses Secure Sockets Layer Protocol and its successor, Transport Layer Security to provide the secure connection between remote users and specific, supported internal resources that you configure at a central site. The security appliance recognizes connections that need to be proxied, and the HTTP server interacts with the authentication subsystem to authenticate users. The network administrator provides access to Web. VPN resources to users on a group basis. Users have no direct access to resources on the internal network. The following sections address getting started with the configuration of Web. VPN access Observing Web. VPN Security Precautions Understanding Features Not Supported for Web.

VPN Authenticating with Digital Certificates Observing Web. VPN Security Precautions Web. VPN connections on the security appliance are very different from remote access IPSec connections, particularly with respect to how they interact with SSL enabled servers, and precautions to reduce security risks. In a Web. VPN connection, the security appliance acts as a proxy between the end user web browser and target web servers. When a Web. VPN user connects to an SSL enabled web server, the security appliance establishes a secure connection and validates the server SSL certificate. The end user browser never receives the presented certificate, so therefore cannot examine and validate the certificate. The current implementation of Web.

VPN on the security appliance does not permit communication with sites that present expired certificates. Nor does the security appliance perform trusted CA certificate validation.

VPN users cannot analyze the certificate an SSL enabled web server presents before communicating with it. To minimize the risks involved with SSL certificates 1. Configure a group policy that consists of all users who need Web. VPN access and enable the Web. VPN feature only for that group policy. Limit Internet access for Web. VPN users. One way to do this is to disable URL entry. Then configure links to specific targets within the private network that you want Web. VPN users to be able to access. Educate users. If an SSL enabled site is not inside the private network, users should not visit this site over a Web. VPN connection. They should open a separate browser window to visit such sites, and use that browser to view the presented certificate. Understanding Features Not Supported for Web. VPN The security appliance does not support the following features for Web. VPN connections DSA certificates the ASA does support RSA certificates. Inspection features under the Modular Policy Framework, inspecting configuration control. Functionality the filter configuration commands provide, including the vpn filter command. NAT, reducing the need for globally unique IP addresses. PAT, permitting multiple outbound sessions appear to originate from a single IP address. Qo. S, rate limiting using the police command and priority queue command. Connection limits, checking either via the static or the Modular Policy Framework set connection command. The established command, allowing return connections from a lower security host to a higher security host if there is already an established connection from the higher level host to the lower level host. Using SSL to Access the Central Site Web. VPN uses SSL and its successor, TLS1 to provide a secure connection between remote users and specific, supported internal resources at a central site. This section includes the following topics Using HTTPS for Web. VPN Sessions Configuring Web. VPN and ASDM on the Same Interface Setting Web. VPN HTTPHTTPS Proxy Configuring SSLTLS Encryption Protocols Using HTTPS for Web. VPN Sessions Establishing Web. VPN sessions requires the following Using HTTPS to access the security appliance or load balancing cluster. In a web browser, users enter the security appliance IP address in the format https address where address is the IP address or DNS hostname of the security appliance interface. Enabling Web. VPN sessions on the security appliance interface that users connect to. To permit Web. VPN sessions on an interface, perform the following steps Step 1 In global configuration mode, enter the webvpn command to enter webvpn mode. Step 2 Enter the enable command with the name of the interface that you want to use for Web. VPN sessions. For example, to enable Web. Thieves And Kings Serial. VPN sessions on the interface called outside, enter the following hostnameconfig webvpn. Configuring Web. VPN and ASDM on the Same Interface The security appliance can support both Web. VPN connections and HTTPS connections for ASDM administrative sessions simultaneously on the same interface. Both HTTPS and Web. VPN use port 4. 43 by default. Therefore, to enable both HTTPS and Web. VPN on the same interface, you must specify a different port number for either HTTPS or Web. VPN. An alternative is to configure Web. VPN and HTTPS on different interfaces. To specify a port for HTTPS, use the port argument of the http server enable command. The following example specifies that HTTPS ASDM sessions use port 4. Web. VPN is also enabled on the outside interface and uses the default port 4. With this configuration, remote users initiate ASDM sessions by entering https lt outsideip 4. To specify a port for Web. VPN, use the port command from webvpn configuration mode. The next example enables Web. VPN on port 4. 44 of the outside interface. HTTPS for ASDM is also configured on the outside interface and uses the default port 4. With this configuration, remote users initiating Web. VPN sessions enter https lt outsideip 4. Setting Web. VPN HTTPHTTPS Proxy The security appliance can terminate HTTPS connections and forward HTTPHTTPS requests to HTTP and HTTPS proxy servers. These servers act as intermediaries between users and the Internet. Requiring all Internet access via a server that the organization controls provides another opportunity for filtering to assure secure Internet access and administrative control.
