NetGuard GuardianPro Remote Management
Port 1500 is typically used for remote management of NetGuard GuardianPro firewalls based on NT4 systems. This port facilitates administrative access, configuration management, and real-time monitoring of firewall status. Designed for legacy environments, it enables system administrators to remotely maintain security policies and respond to network events efficiently..
Port 1500 has historically been associated with remote management interfaces of NetGuard GuardianPro firewalls running on Windows NT4. Administrators utilize this port over TCP to establish a management session, which allows them to configure rules, monitor network activity, and update firewall policies. The communication through this port typically involves proprietary protocols suited to the GuardianPro ecosystem.
The remote management service running on port 1500 listens for incoming connections on the firewall’s management interface. These connections grant privileged access for administrative tasks, which, in legacy setups, might additionally integrate with other NT4 services like RPC or SMB for configuration and logging. Because it operates over TCP, the protocol supports reliable transmission, which is critical when applying configuration changes remotely.
Given its role in network security infrastructure, the port is generally exposed only within trusted administrative networks or over secure out-of-band management channels. However, in many older deployments, insufficient segmentation might leave it inadvertently accessible to broader network segments, increasing potential attack surfaces.
