SOCKS implementation for the SOHO 6

SOCKS is a network proxy filter that works with SOCKS-aware applications. A typical SOCKS-dependent application requires that several sockets be opened and made available to the Internet. When a SOCKS-aware application (ICQ is an example) registers with the SOCKS server, SOCKS is able to manage the need of the application to have many ports open.

To use an application with SOCKS, configure the application with the SOCKS server information.

Setting up your SOCKS application for use with the SOHO 6 requires no reconfiguration of the SOHO 6 appliance itself. Your SOHO 6 acts as the SOCKS proxy. You must, however, configure your application to be compliant with the SOHO 6 implementation of SOCKS version 5.
