  - Specify upstream DNS (kind of a plain DNS proxy)
 - IPv6 (behind NATed LAN, like IPv4)
 - Creating WiFi hotspot:
-  - Wifi 3/4/5/6
-  - 2.4GHz, 5GHz
  - 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)
- Detect and prevent interference from following Linux system daemons:
-  - NetworkManager (handle interface (un)managed status)
-  - firewalld (use temporary `trusted` zone)
- Instances managing. You can run multiple instances, to create different sub-networks.

 ## TODO
+
+Sooner is better:
+- Detect firewalld and make sure it won't interfere our interface
+
+Future:
 - WPA3
 - Global IPv6
+- Explictly ban forwarding if not needed
+- Bring bridging method back
