# 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).

- Channel selecting
- Choose encryptions: WPA2/WPA, WPA2, WPA, No encryption
- Create AP on the same interface you are getting Internet (usually require same channel)
- Transparent proxy (redsocks)
- Transparent DNS proxy (hijack port 53 packets)
- Compatible with NetworkManager (automatically set interface as unmanaged)
- Detect NetworkManager and make sure it won't interfere (handle interface (un)managed status)
- You can run many instances, to create many different networks. Has instances managing feature.

🤝 Bisides, thank [create_ap](https://github.com/oblique/create_ap) by [oblique](https://github.com/oblique). This script was forked from create\_ap. Now they are quite different. (See `history` branch for how I modified create_ap). 🤝 Also thank those who contributed to that project.
👨‍💻 You can be contributor, too! 🍃 There're some TO-DOs listed, at both above and in the code file. Also some unfulfilled enhancements in the Issues. Your name can be here!
