Spell out your words.

And if you want to do this, load Squid, which is what you're looking for. Type in "yum install squid". Read one of the many how-to guides on how to configure it to suit your needs. Since you don't say what kind of access, authentication, etc., can't be more specific.

Again, you are providing no details, so how can anyone say?

You can do port-forwarding using iptables, but why bother? You'd have a pretty big list of ports to forward, no authentication, no tracking or anything else. If it's just two machines, you'd be better of spending $40 on a small router/swtich from Linksys/dLink, etc., and use it to share the connection.

the linux box is located in another building . It has the access to internet with eth1 configuration. I have full access to my linux system.
there are many routers/hubs between these two systems.

Still, no real details.

As said in the first post, set up Squid.

my problem is if i setup squid i can access internet but cant play games like poker(face book) which uses 9339 port and other games.But i can play/access these games on linux pc but not on my windows pc which connects to squid for internet access.

Is there any other way like putty/ssh connection to play games like these?

You can open or allow any ports you want on a server you control, so not really seeing what the problem is.

Also, if this is for WORK, why are you playing games and using Facebook, while you're supposed to be working?

See previous post, about opening whatever ports you want, and try to get a clear picture of what a proxy server does, and how. If you just point a browser to it, that's all that'll get out. ANY and all applications need to be set up to use the proxy server. Read the Squid documentation about how to open additional ports, and how to do forwarding.
