you can do it in two ways..
1. setup a firewall (iptables) and add some
rules that would block incomming request for
specific IP's

iptables -A input -i NIC_INTERFACE -p tcp -s
BANNED_IPorRANGE --dport PROXY_PORT -j REJECT

2. if your using squid you may want to check the
squid.conf

While iptables or ipchains will most certainly do the trick, you might try looking at squidGuard (assuming the proxy you're using is squid). It offers a few more "bells and whistles" than either iptables or ipchains and is very easily configured.
