Step

At home

1. Install cygwin and openssh package in my home's PC
2. Install pagekite and run following command as a scheduled job python.exe pagekite.py 22 ssh:YOU.pagekite.me

At workstation

1. Use putty to login YOU.pagekite.me:22 through http proxy YOU.pagekite.me:443
2. Create dynamic port forwarding -D1080 in localhost
3. In putty: Connection -> Seconds between keepalives should be larger than 0(such as 10)
4. Setup firefox to use socks proxy localhost:1080

Another method(Using Squid)

1. at home: install squid
2. at workstation: using putty to create local port forwarding: -L3128:localhost:3128
3. Setup firefox to use http proxy localhost:3128

PS: Proxy tools

connect or netcat or corkscrew or nc
proxycap or httptunnel
stunnel
