Dos recomendaciones que probe y funcionan son
Winproxy al igual que
Sygate .
Winproxy tiene mejor interface y mas opciones pero es dificil de conseguir los cracks de las ultimas versiones y suelen ser problematicos.
Otras recomendaciones pueden ser los gratuitos:

Can pass requests to other SOCKS servers! - Check the "Chain to other SOCKS" box to do this. Can log all data that passes through it! - Check the "log" box.

SpoonProxy (Pi-Soft Consulting, sproxy16.exe, 510KB)
http://www.pi-soft.com/
(Proxy. See description below)
Enables every machine on your network to access internet resources through one internet connection thereby saving you tons of money in telephone and ISP costs. It runs in a small amount of memory (you will hardly know it's running), yet it is an industrial-strength proxy server that is incredibly easy to set up, is fully customizable, and has excellent online help. The shareware version is fully functional indefinitely (no expire for basic proxy operations), limited only by the number of simultaneous connections it allows. So for a small home network, SpoonProxy is basically free. Supports HTTP, FTP, POP3, SMTP, SOCKS4 and 5, incoming and outgoing IP restriction, auto-dial on demand and a port mapping wizard for easy configuration.
SpoonProxy is fully-functional in this trial version and will not expire. However, it is limited to one user connection at a time until registration and SOCKS4 and SOCKS5 support will stop working after 30 days. So, for a small two machine home network, SpoonProxy is basically free.
