# Linux-router
|
||||
|
||||
Set Linux as router in one command. Able to Provide Internet, or create Wifi hotspot. Support transparent proxy (redsocks). Also useful for routing VM/containers.

Set Linux as router in one command. Able to provide Internet, or create WiFi hotspot. Support transparent proxy (redsocks). Also useful for routing VM/containers.
|
||||
|
||||
It wraps `iptables`, `dnsmasq` etc. stuff. Use in one command, restore in one command or by `control-c` (or even by closing terminal window).
