# Linux-router
Share your Linux's Internet access to other devices.
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.
The goal is to easily set/unset your Linux PC/embedded device as a gateway/hotspot/transparent proxy. It wraps the complicated `iptables`, `dnsmasq` etc. stuff. Use in one command, restore by `control-c`.
