Command line vpn configuration

Hi I’ve installed atvflash but for some reason, my ISP (virginmedia uk) has network issues upsteream so I cannot directly access atvflash.com. To access the site from my pc, I need to use hotspotshield as a proxy, can I configure hotspotshield via command line on the atv so that I can complete the atvflash installation

Any help appreciated

Thanks
