Hi guyz .. I'm new here ..

here's the thing,

I'm connecting to the internet thru a LAN .. I use the server's IP as a proxy in internet explorer which only allows me to browse and chat on msn .. but I can't use Audio or Camera, neither Kaza and P2P clients ..

is there a way to screw the proxy or the server to open the ports so I can get audio on msn or yahoo n other stuff ??

by the way, the guys that own the network are not professionals .. they can hardly manage to start the server and shut it down ..

PLEASE HELP !

thanks
