You can use TCP Port Mapper to automatically switch your web browser's proxy setting and surf the web anonymously.

1. In tcpportmap.ini configure ListenPort setting: ListenPort=3128 (listen incoming connections on port 3128).
2. In tcpportmap.ini configure MapFromFile setting: MapFromFile=c:\proxies.txt (load proxies from file c:\proxies.txt).
3. Setting ProxyMode should not be present in tcpportmap.ini or it can be equal NONE: ProxyMode=NONE (turn off Proxy Mode).
4. You can configure SwitchMapConnections setting: SwitchMapConnections=10 (automatically switch to the next proxy each 10 connections).
5. Run TCPPortMap.exe.
6. Configure your web browser's proxy settings to use proxy 127.0.0.1:3128

TCP Port Mapper allows to share your list of proxies. Example of settings in tcpportmap.ini:

ListenPort=3128-3129
MapArray=127.0.0.1:8080,127.0.0.1:8081

In this example: TCP Port Mapper will listen incoming connections on ports 3128 and 3129. For all connections to port 3128 it will use proxy 127.0.0.1:8080. For all connections to port 3129 it will use proxy 127.0.0.1:8081
