+      Features:

+      - Create a NATed sub-network
+      - Provide Internet
+      - DHCP server and RA
+      - DNS server
+      - IPv6 (behind NATed LAN, like IPv4)
+      - Creating Wifi hotspot:
+        - Channel selecting
+        - Choose encryptions: WPA2/WPA, WPA2, WPA, No encryption
+        - Create AP on the same interface you are getting Internet (require same channel)
+      - Transparent proxy (redsocks)
+      - DNS proxy
+      - Compatible with NetworkManager (automatically set interface as unmanaged)
