Privoxy

Privoxy is a non-caching web proxy with advanced filtering capabilities for enhancing privacy, modifying web page data and HTTP headers, controlling access, and removing ads and other obnoxious Internet junk. Privoxy has a flexible configuration and can be customized to suit individual needs and tastes. It has application for both stand-alone systems and multi-user networks.

Use opkg to install the privoxy package.

opkg update
opkg install privoxy
vi /etc/config/privoxy
/etc/init.d/privoxy enable
/etc/init.d/privoxy start

Since OpenWrt Chaos Calmer (trunk) there is also available a corresponding LuCI application to support setting of Privoxy configuration via Web-GUI.
Require Privoxy v3.0.22 package

Change the listen-address in /etc/config/privoxy to your router ip address such as listen-address 192.168.1.1:8118. You need change default setting permit-access 192.168.1.0/24 to something else if you use a different subnet.

Last you need start up the proxy server with command /etc/init.d/privoxy start.
To have it start on boot, enable the init script with /etc/init.d/privoxy enable.

You'll need to add the proxy information to your internet browser to use it.

Since OpenWrt Chaos Calmer (trunk) / Privoxy v3.0.22 the /etc/privoxy/config file is no longer used
The configuration was moved to the UCI configuration /etc/config/privoxy.
All Privoxy configuration variables are still supported.

Due to UCI does not support variables names with “-” this needs to be replaced by “_”
Sample: privoxy “listen-address” must be UCI “listen_address”

If you add entries please use:
* option for options with one parameter (option confdir)
* list for options with multiple parameters (list listen_address)
* special handling for debug option: privoxy option “debug 1024” must be UCI “option debug_1024 '1' “
Please see sample below

Below is an example of the /etc/privoxy/config file (deprecated--see below for current version)
