Gmod Fast DL Self Hosting Possible ?

Is it possible somehow to upload my required server files to the players connecting like fast DL, without having to rent a webspace of somekind ? because i have 150 mb/s Upload and i don’t wanna pay 4$ a month just so players can download files to the server, i mean there must be somekind of software or something i can do to host my own Fast download from the same server i am hosting my Gmod server. ( i am hosting the gmod server too )
