By default, all inbound connections from all network interfaces to the device are allowed. To improve data security, a firewall must be setup. This can be done by creating a file called firewall.sh to the /opt/user/userapp/etc directory. The Data Security tab in MultiTool Creator provides an easy way to setup the file.
In the Basic tab, connections to specified applications/protocols can be allowed. All connections that have not been selected are denied. Check the boxes to allow inbound connections. If an unlisted protocol is needed, use the Advanced tab.
Firewall settings can be reset with Reset to Default 
icon.
