Experimente o WideCap , gratuito desde 06 de maio de 2009:
WideCap - is system proxifier. It was created as extended version of FreeCap program. But WideCap IS NOT a branch or new FreeCap version.
WideCap is fully functional Winsock Service and Namespace provider. That means simply integration into your network subsystem. Forget about this ugly FreeCap's injection, needle to run all programs throught FreeCap, possible errors and incompatible with some firewalls and anti-viruses. WideCap acts as virtual network driver covering all your TCP/IP activity. No launchers - just run your program as usual and work via proxy.
