UVIYN Firewall Settings

Mods with no hardware modifications (software only)

Add port 80 and 22 to firewall rules to access it from external wwan interface
Since the UVIYN hotspot is connected to your local wifi (internet) you may want to access it from there. For that you need to forward port 80 (webinterface) and port 22 (ssh) from wwan to lan on the UVIYN Hotspot.
