Internet protection By-pass

Okay i need help to By-pass this internet blockade. I am trying to play WoW at Warmane at my work. But, the IT sector has put the blockade on the IP or whatever, we can watch Twitch, Youtube, Download (from normal download sites), open forums, sites, even online watching platforms (like HBO, Netflix), but i want that extra one, we can't download torrents nor get online (on Battle.net application) nor get on Warmane WoW server. I would like someone to help me if there is a possibility to pass this, some VPN or something. I have laptop for work so i take it home where i can download any stuff from anywhere i just need a way to bypass this blockade on the work.

Any suggestions are welcome !

Thanks..
