How I could redirect all my traffic to Tor network?
You can't redirect ALL traffic into TOR - if you mean all traffic at the IP level. (so all icmp, tcp and udp traffic), because you need basic routing via the internet - e.g. you need route TOR packets to neigbohrs. TOR is an VIRTUAL network using onion routing (SOCKS), so you need explicitly route packets into TOR.

If you mean "route ALL web-browsing traffic" into tor-network, the easiest way is using Firefox and get a torbutton plugin into firefox.

After installing the plugin, it is enough:


start Vidalia, and
activate "torbutton" in the Firefox. (bottom right corner).


BTW, it is a good practice:
  - use Safari (or Chrome) for you common browsing, and
  - use Firefox for anonymous things (you can setup Firefox start into "private browsing" mode, you should disable cookies and so on...

BEWARE - if your browser gets a cookie via TOR and after it send this cookie via normal browsing session - you get the idea :)
