Huge number of answers, but I'll give mine. At work I would use a Ubiquity or untangle or Mikrotik or something, but for home use yeah, for less than the cost of one of those that will do gigabit you can get an old server (small), put PfSense on it, and have something far more flexible than an Asus or Netgear. For instance:. Try setting port 80 only coming IN from certain IP with one of those? Not even sure you can do that on a Ubiquity. Try to find something that can do that AND do UPNP so you kid can play Black Ops 3...
