# 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`.
|
||||
It wraps `iptables`, `dnsmasq` etc. stuff. Use in one command, restore in one command or by `control-c`.
|
||||
|
||||
It works on wired, wireless and virtual networks.
|
||||
|
||||
## Features
|
||||
|
||||
Basic features:
|
||||
|
||||
- Create a NATed sub-network
|
||||
- Share Internet to the sub-network
|
||||
- DHCP server
|
||||
- Provide Internet
|
||||
- DHCP server and RA
|
||||
- DNS server
|
||||
- IPv6 (NAT only for now)
|
||||
- Creating Wifi hotspot:
|
||||
- Channel selecting
|
||||
- Choose encryptions: WPA2/WPA, WPA2, WPA, No encryption
