Al wants to get a router that can run Tomato or DD-WRT, so he can run VPNs through it because mesh routers aren't open source. Leo says a better option is to use an old computer as his router. pfSense is a good open source router app that can do that. It'll give him far more powerful hardware that can do what he would want it to do. He can even use a Raspberry Pi for it. Then he will have more choices for running VPNs on it. Leo also suggests going to the Tomato or DD-WRT site to see what routers are supported by it, and then choose one. There's no point in buying a mesh router to run Tomato since he is buying a lot of capabilities he won't use.
