In Client mode, the user specifies a remote host (IP or domain) and port to perform advanced connectivity diagnostics.

The Client interface allows you to:

• measure latency (RTT / ping) in real time

• perform traceroute with ICMP and automatic TCP fallback

• test DNS resolution and DNS response time

• verify open or closed TCP ports

• run upload and download SpeedTest

• monitor active TCP connections

• analyze inbound and outbound traffic in Mbps

Real-time graphs visualize:

• network traffic (In / Out)

• number of active TCP connections

• network latency (RTT)

This makes APTOFI Net Test suitable for network troubleshooting, bandwidth validation, performance benchmarking, VPN diagnostics, server reachability checks, and infrastructure monitoring.

Server mode allows you to instantly deploy a lightweight test server for remote connectivity validation and throughput measurement.

The Server interface enables:

• remote port accessibility testing

• firewall and NAT rule validation

• bandwidth measurement between endpoints

• internal network diagnostics

• VPN tunnel performance testing

• infrastructure connectivity verification

When used together with Client mode, APTOFI Net Test provides a controlled environment for full end-to-end network diagnostics across LAN, WAN, and VPN environments.

Built-in graphs display:

traffic (In / Out),
active TCP connections,
network latency (RTT).

The program is designed as a modern alternative to classic diagnostic utilities such as WinMTR, while offering extended functionality including integrated speed testing, live traffic monitoring, and a dedicated server mode within a single Windows application.

A minimalist interface, fixed pixel grid layout, low system resource consumption, and zero unnecessary background services make it a reliable tool for daily operational diagnostics and rapid troubleshooting in production and test environments.
