Does a free alternative to Proxifier or ProxyCap exist?

When on a hotel's hotspot, the majority of ports are closed, except 80, 443 and 22. I would like to connect to my FTP, or connect Steam to play my games, etc. I tested ProxyCap and Proxifier which redirected all my traffic to my sock server at home, but trials versions has expired, and I don't want to pay for something that I use a few weeks in a year. I know I can set the proxies settings in my Mac settings, but all the applications don't use it (like Steam). Does a free alternative of ProxyCap and Proxifier exist on MacOSX?
