Limited storage capacity of the device cannot store many logs for a long time. If you need to
save logs for long, enable online log to ensure key logs are synced to the online log server for
easy back tracking.
13. Building Safe Network Environment
To keep the device safer and reduce network risks, we recommend you to:
Turn off the port mapping of the router to prevent external networks from directly accessing
services of router intranet devices.
Divide network into different partitions as needed: If two subnetworks do not have to
establish communications, use VLAN or gatekeeper for network division.
Build up the 802.1x access authentication to reduce the risk of illegal terminals connecting
with your private networks.
Enable device IP/MAC address filtering to limit the hosts that can access the device.
