SERVER PORTS & PORT SCANNING

RingQ Portal — Checking Port Status, Internal & External Scanning

Overview

The Server Ports panel in RingQ allows administrators to view the full list of ports used by the system and check their live status — both from inside the server (Internal scan) and from the public internet (External scan). This is useful for verifying firewall rules, diagnosing connectivity issues, and confirming that critical services such as SIP, RTP media, and WebRTC are reachable.

Step 1 — Navigate to Server Ports

From the RingQ portal, go to General Setting. Scroll down to the Advanced section and click the Ports tile (highlighted below).

Fig. 1 — General Setting page. Click the Ports tile under the Advanced section (highlighted in red).

Step 2 — Understanding the Server Ports Panel

The Server Ports panel lists every port used by RingQ, grouped into categories accessible via the filter tabs at the top. Each row shows the port number, protocol, direction, service name, current status, and a Scan button to test that port individually.

Fig. 2 — Server Ports panel (Internal view). Filter tabs across the top allow filtering by service category. The Scan icon (red box) tests an individual port.

The filter tabs available are:

The Status column uses the following indicators:

Step 3 — Running an Internal Port Scan

Click the Internal button (top-right of the panel) to switch to the internal scan view. Then click Scan All (Internal) to test all ports from within the server itself. A live console output will display progress as each port is checked.

Fig. 3 — Internal scan in progress. The dark console shows real-time port checking (127/170 complete). Results update in the table below as each port is tested.

Once complete, each port row in the table will show its updated status. You can also scan a single port at any time by clicking the Scan icon on that row.

⚠ NOTE

The Internal scan tests ports from within the server — it does not confirm whether those ports are reachable from the internet. A port showing "Listening" internally may still be blocked by an upstream firewall. Use the External scan to verify public reachability.

Step 4 — Running an External Port Scan

Click the External button (top-right of the panel) to switch to the external scan view. Then click Scan All (External) to probe all ports from RingQ's own external checker. This confirms which ports are reachable from the public internet.

Fig. 4 — External scan complete (170/170 ports checked). The External button and Scan All (External) are highlighted in red. Results show Egress OK, Listening, or Not detected.

The external scan note at the top of the panel reads: "External reachability is probed from RingQ's own checker (download-global). TCP ports give real verdicts; UDP is best-effort. Outbound egress is tested live."

⚠ NOTE

UDP port results in the External scan are best-effort only and may show "Not detected" even when the port is open, depending on firewall and NAT configuration. TCP port results are definitive.
