My company has a WLAN, which i can cannot to, however it uses a HTTP proxy to access the Internet. Is there some setting or an application that will allow me to enter the proxy settings and browse through the proxy?????

who do you know managing your network, convince them to set an iprange to connect straight out through he firewal/proxy setup with a tie in to vpn to give security if there picky. seemed the easieast way here atleast.
