most common situations:
1. To connect from the WinRoute host it is necessary to use the proxy server of your
ISP.
Proxy server included in WinRoute can forward all queries to so called parent proxy
server).
2. Internet connection is performed via a dial-up and access to certain Web pages is
blocked (refer to chapter 10.2). If a direct connection is used, the line will be dialed
before the HTTP query could be detected (line is dialed upon a DNS query or upon
a client’s request demanding connection to a Web server). If a user connects to
a forbidden Web page, WinRoute dials the line and blocks access to the page the
line is dialed but the page is not opened.
Proxy server can receive and process clients’ queries locally. The line will not be
dialed if access to the requested page is forbidden.
3. WinRoute is deployed within a network with many hosts where proxy server has been
used. It would be too complex and time-consuming to re-configure all the hosts.
The Internet connection functionality is kept if proxy server is used it is not
necessary to edit configuration of individual hosts (or only some hosts should be
re-configured).
The WinRoute’s proxy server can be used for HTTP, HTTPS and FTP protocols. Proxy
server does not support the SOCKS protocol ( a special protocol used for communication
between the client and the proxy server).
Note: For detailed information on using FTP on the WinRoute’s proxy server, refer to
chapter 23.6.
Proxy Server Configuration
To configure proxy server parameters open the Proxy server tab in Configuration
Content Filtering HTTP Policy.
Enable non-transparent proxy server
This option enables the HTTP proxy server in WinRoute on the port inserted in the
Port entry (3128 port is set by the default).
Warning : If you use a port number that is already used by another service or
application, WinRoute will accept this port, however, the proxy server will not be
able to run and the following report will be logged into the Error log (refer to
chapter 20.8):
failed to bind to port 3128: another application is using this
port
