web proxy

Hi
I am new to this.I tried using web proxy with the following configuration:

ip proxy
set enabled=yes
set src-address=0.0.0.0
set port=8080
set parent-proxy=0.0.0.0
set parent-proxy-port=0
set cache-administrator=“webmaster”
set max-cache-size=none
set cache-on-disk=no
set max-client-connections=600
set max-server-connections=600
set max-fresh-time=3d
set always-from-cache=no
set cache-hit-dscp=4
set serialize-connections=no"

/ip proxy access
add dst-host=www.yahoo.com action=deny

My question is
How to block particular website for particular ip and how to make it as open proxy.

You can set multiple ports, so you could listen to ports 8080 and 8081. Then you can check the proxy port used in the proxy access rule. That lets you redirect traffic from specific users to different proxy ports, and have certain rules only apply to them.

What do you mean by “open proxy”? That anyone can use it? If you’re not blocking access to the ports the proxy is listening on in the ‘input’ chain then you’re already set.
