SOCKS proxy traffic redirect

view story

http://serverfault.com – I have a WoW server hosted on a Linux server. The problem is that I get a lot of DDOS attacks and I want to figure out a way of protecting my server. So... Let's say that my server address is I wonder if there is any solution to use let's say 10 SOCKS proxies with different IPs and when a user wants to connect to my server, he will pick one of these proxies, then all the communication done to SOCKS proxy to be redirected to my actual server IP. Can you advise me in this situation? Thanks! (HowTos)
