The AT-AR220E will not allow you to forward enough ports, to run Synology RS2212+. You should try using the DMZ portion of this router if it is available. Alternatively you can try switching the router to bridged mode. You will need to contact your ISP to switch to bridged mode, so they can make the required changed on their end.
