我的旁路由/透明代理配置

There are times when you need to filter out what some hosts in the network can or cannot do. When you have a router running OpenWRT this can be done at the firewall level. But if you're not much into advanced configuration and just want to completely block out some network hosts from reaching the internet (and hence phoning home) then it's a lot simpler to do this directly from the DHCP and simply leave them without a DNS and gateway configuration.
