Introduction
- Diagnostic Tools provide useful tools for viewing or diagnosing the router. Click Diagnostic Tools to enter the following page. The following sections will explain the details for each tool.
Descriptions
ISDN / PPPoE / PPTP Diagnostics
- Click here to open the following page. The page shown here is for reference only; individual networks will show different results.
- The page has been grouped into two subgroups: the upper is for ISDN link status, the lower is for broadband access status.
- Refresh: To obtain the latest information, click here to reload the page.
- ISDN Link Status: If the link is active, this field will show UP. Otherwise, it shows DOWN.
- Dial ISDN: Clicking here causes the router to dial to the preset ISP. Click Internet Access Setup > Dial to a Single ISP to configure dial-up settings.
- Activity: Displays the connection name for each B channel. If the B channel is idle, it will show Idle.
- Drop B1: Click to disconnect the B1 channel.
- Drop B2: Click to disconnect the B2 channel.
- Broadband Access Mode/Status: Display the broadband access mode and status. If the broadband connection is active, it will show PPPoE, PPPoA, Static IP, or DHCP Client depending on which access mode is enabled.
- If the connection is idle, it will show “—”.
- WAN IP Address: The WAN IP address for the active connection.
- Dial PPPoE or PPPoA: Click to force the router to establish a PPPoE or PPPoA connection.
- Drop PPPoE or PPPoA: Click to force the router to disconnect the current active PPPoE or PPPoA connection.
Triggered Dial-out Packet Header
- Triggered Dial-out Packet Header shows the last IP packet header that triggered the router to dial out.

- View Routing Table
- Click View Routing Table to view the router’s routing table.
- The table provides current IP routing information held in the router. To the left of each routing rule, you will see a key.
These keys are defined as:
- C — Directly connected.
- S — Static route.
- R — RIP.
- * — Default route.
- ~ — Routes for private routing domain.
To the right of each routing rule, you will see an interface identifier:
- IF0 — Local LAN interface.
- IF1 — ISDN B1 channel.
- IF2 — ISDN B2 channel.
- IF3 — WAN interface.
- Refresh: Click to reload the page.
View ARP Cache Table
- Click View ARP Cache Table to view the ARP (Address Resolution Protocol) cache held in the router. The table shows a mapping between an Ethernet hardware address (MAC Address) and an IP address.
- Refresh: Click to reload the page.
View DHCP Assigned IP Addresses
- View DHCP Assigned IP Addresses provides information on IP address assignments. This information helps diagnose network problems, such as IP address conflicts, etc.
View NAT Port Redirection Running Table
- If you have configured Port Redirection (under NAT Setup), click to verify that your settings are correct for redirecting specific port numbers to specified internal users.
View NAT Active Sessions Table
- As the router accesses the Internet through the built-in NAT engine, click View NAT Active Sessions Table to see which active outgoing sessions are online.
- Each line across the screen indicates an active session.
The following information is displayed:
- Private IP, Port: The internal user’s (PC’s) IP address and port number. #Pseudo Port: The public port number.
- Peer IP, Port: The peer user’s (PC’s) IP address and port number.
- Ifno: Stands for interface number.
The definition is listed below:
- 0 — LAN interface.
- 1 — B1 interface
- 2 — B2 interface.
- 3 — WAN interface.
ADSL Spectrum Analysis (V2600 only)
- ADSL uses 249 channels(DMT modulation) for data transmission. It will show bits, gain, and SNR spectrum analysis for every Bin.
Frequently Asked Questions
How often should I refresh the diagnostic tools page?
Refresh the page whenever you need to obtain the latest information or update the status of connections.
What do I do if the ISDN link status shows as DOWN?
If the ISDN link status shows as DOWN, check your physical connections and settings. You may need to troubleshoot or contact your ISP for assistance.
How can I verify if my port redirection settings are correct?
