In your control panel you have an option that says Sync FastDL, simply run that and it should update all of your files on the remote server. Now to point your server to that redirect change the following in your server config. Locate the 2 lines that look like this below
seta sv_wwwDownload "0"
seta sv_wwwBaseURL ""
and change that to
seta sv_wwwDownload "1"
seta sv_wwwBaseURL "http://fastdl.eoreality.net/yourserverip_port"
your server ip must be your game server ip and port must be your game port normally 27015
