Chapter 16 - Configuring Web Proxy Settings
This chapter describes how to configure web proxy settings.

Web Proxy Settings

Setting the WPAD CURL

The SMS2000 supports DNS based web proxy auto discovery. The wpad.dat file must
ensure that the subscriber does not use the proxy when communicating with the
SMS2000 or the OCS.
Note: The proxy server must not be in any allow-net, or the subscriber will
have access to every server to which the proxy server will proxy (normally most
of the Internet).
Servers for which an allow-net entry exists, but which can only be contacted through the
proxy server, will be unreachable unless subscribers have total access to the proxy server.
To implement a "wall garden" or "allow-nets" for a network requires that the subscribers
connect to those locations via the proxy server, it is possible to supply a different
wpad.dat proxy configuration file for each group, pointing the "walled" group to a more
restrictive proxy server. Contact Tut Systems for more information.
To configure the web proxy auto discovery configuration URL (CURL) for subscribers in
the current group, use this command:
set wpad-curl [off | on | on curl]
This example loads the wpad.dat file onto the SMS2000 from the OCS server at IP
address 10.228.10.233, then enables the wpad support.
sms2000% load web http://10.228.10.233/wpad.dat
sms2000% set wpad-curl on

Setting the WPAD Timeout

Internet Explorer will not refresh the wpad.dat file while running. Once closed and
opened, it will correctly refresh a wpad.dat file if the previously cached file was timed
out.
