Local Networks

Overview

The Local Networks tab provides functionality within a network management solution that allows users to specify network ranges considered internal or part of their local network infrastructure. This feature helps categorize IP addresses as either internal or external based on predefined rules.

Defining local network ranges is essential for:

  • Network monitoring – Helps track and analyze internal traffic;
  • Access control – Ensures security policies are properly enforced;
  • Security management – Identifies external threats more efficiently;
  • Accurate reporting – Provides clear insights into internal vs. external network traffic.

Default Network Ranges

By default, the system includes the following local network ranges in CIDR (Classless Inter-Domain Routing) format:

  • 10.0.0.0/8
  • 172.16.0.0/12
  • 192.168.0.0/16

Editing Local Network Ranges

To modify the predefined network ranges, follow these steps:

1.Navigate to the Local Networks Tab

  • The Local Networks option is accessible from the Administration tab by clicking the Alt Image button in the left-side panel of the Web Interface.

2.Access the Edit Mode

  • Click the Edit button to enable modifications.
  • A list of existing network ranges will be displayed in CIDR format.
  • Enter the network range in CIDR format (e.g., 192.168.1.0/24).
  • Click Save to confirm the modifications.

Identifying External IP Addresses

Determining whether an IP address is external involves checking the traffic logs:

  • To determine whether an IP address is external, navigate to Traffic tab > Traffic View.

  • Locate the _OS7.isExternalTraffic field:

    • If the External Traffic(_OS7.isExternalTraffic) field displays true, the IP address is classified as external.

    • If the External Traffic (_OS7.isExternalTraffic) field displays false, the IP address is classified as internal.
