Got a new Router over the weekend. Old one just wasn't keeping up with streaming and a dozen devices connected plus was about 8 years old. Couldn't access weekendgunnit and today I saw the router was blocking weekendgunnit.win.
You have to go to Settings>Security and turn off armor.
Consumer routers are terrible. Get something that you can flash an open source firmware to (ddwrt etc) or something like a ubiquity router or enterprise gear. Never trust the security of your network to basic consumer software.
