Network Resources Overview

Network Resources are the granular components of a trusted network that can be accessed using the SMA/SRA appliance. Network Resources can be
pre-defined by the administrator and assigned to users or groups as bookmarks, or users can define and bookmark their own Network Resources.
The following sections describe types of network resources supported by the SMA/SRA appliance:
•

HTTP (Web) and Secure HTTPS (Web)

•

Telnet

• SSHv2
• FTP (Web)
• File Shares (CIFS)
• Remote Desktop Protocols and Virtual Network Computing
• Application Protocols Using RDP
• Microsoft Outlook Web Access
• Windows SharePoint Services
• Lotus Domino Web Access
• Citrix Portal
HTTP (Web) and Secure HTTPS (Web)
The SMA/SRA appliance provides proxy access to an HTTP or HTTPS server on the internal network, Internet, or any other network segment that can
be reached by the appliance. The remote user communicates with the SMA/SRA appliance using HTTPS and requests a URL. The URL is then retrieved
over HTTP by the SMA/SRA appliance. The URL is transformed as needed, and returned encrypted to the remote user.
The Secure Mobile Access administrator can configure Web (HTTP) or Secure Web (HTTPS) bookmarks to allow user access to web-based resources
and applications such as Microsoft OWA Premium, Windows SharePoint 2007, Novell Groupwise Web Access 7.0, or Domino Web Access 8.0.1,
8.5.1, and 8.5.2 with HTTP(S) reverse proxy support. Reverse-proxy bookmarks also support the HTTP 1.1 protocol and connection persistence.
HTTPS bookmarks on SMA 400 and SRA 4600 appliances support keys of up to 2048 bits.
HTTP(S) caching is supported on the SMA/SRA appliance for use when it is acting as a proxy Web server deployed between a remote user and a local
Web server. The proxy is allowed to cache HTTP(S) content on the SMA/SRA appliance which the internal Web server deems cacheable based on the
HTTP(S) protocol specifications. For subsequent requests, the cached content is returned only after ensuring that the user is authenticated with the
SMA/SRA appliance and is cleared for access by the access policies. However, Secure Mobile Access optimizes traffic to the backend Web server by
using TCP connection multiplexing, where a single TCP connection is used for multiple user sessions to the same web server. Caching is predominantly
used for static Web content like JavaScript files, style sheets, and images. The proxy can parse HTML/JavaScript/CSS documents of indefinite length. The
administrator can enable or disable caching, flush cached content and set the maximum size for the cache.
Content received by the SMA/SRA appliance from the local Web server is compressed using gzip before sending it over the Internet to the remote client.
Compressing content sent from the appliance saves bandwidth and results in higher throughput. Furthermore, only compressed content is cached, saving
nearly 40-50 percent of the required memory. Note that gzip compression is not available on the local (clear text side) of the SMA/SRA appliance, or for
HTTPS requests from the remote client.
Telnet
Java is being deprecated. Going forward, use HTML5 bookmarks. 8.6 utilizes HTML5 by default.
To enable Java for legacy support, call SonicWall Customer Support for assistance. Note that Java will not be supported in the future.
Telnet client is delivered through the remote user's Web browser. The remote user can specify the IP address of any accessible Telnet server and the
SMA/SRA appliance makes a connection to the server. Communication between the user over SSL and the server is proxied using native Telnet. The
Telnet applet supports MS JVM (Microsoft Java Virtual Machine) in Internet Explorer, and requires Sun Java Runtime Environment (JRE) 1.1 or higher
