Troubleshooting: Not Connecting to VPN Server on Windows Server 2019 STD with Static IP and Dynamic Client IPs

Title: Connecting Windows Server 2019 Standard with Software Clients Having Dynamic IPs to the Internet via a Static IP TDL-TD Modem

Introduction

This article will guide you through the process of connecting a Windows Server 2019 Standard server with software clients having dynamic IPs to the internet via a static IP TDL-TD modem.

Prerequisites

• A Windows Server 2019 Standard server with the necessary software installed
• A TDL-TD modem with a static IP
• Software clients with dynamic IPs

Steps to Connect the Server to the Internet

1. Configure the TDL-TD Modem

   • Connect the TDL-TD modem to your computer and power it on.
   • Open a web browser and enter the modem's IP address in the address bar. The default IP is usually 192.168.1.1.
   • Log in to the modem using the default username and password (usually 'admin' for both).
   • Navigate to the 'Network' or 'Internet' settings and find the 'Static IP' section.
   • Enter the static IP, subnet mask, default gateway, and DNS server addresses provided by your Internet Service Provider (ISP).
   • Save the changes and reboot the modem.

2. Configure the Windows Server 2019 Server

   • Open the 'Network and Sharing Center' by right-clicking on the network icon in the system tray and selecting 'Open Network and Sharing Center'.
   • Click on 'Change adapter settings' on the left side.
   • Right-click on the network adapter connected to the modem and select 'Properties'.
   • Double-click on 'Internet Protocol Version 4 (TCP/IPv4)' in the list.
   • Select 'Use the following IP address' and enter the static IP address provided by your ISP.
   • Select 'Use the following DNS server addresses' and enter the DNS server addresses provided by your ISP.
   • Click 'OK' to save the changes.

3. Configure the Software Clients

   • On each software client, open the 'Network and Sharing Center'.
   • Click on 'Change adapter settings' on the left side.
   • Right-click on the network adapter and select 'Properties'.
   • Double-click on 'Internet Protocol Version 4 (TCP/IPv4)' in the list.
   • Select 'Obtain an IP address automatically' and 'Obtain DNS server address automatically'.
   • Click 'OK' to save the changes.

4. Verify the Connection

   • On the server, open a command prompt and type 'ping [website]' to test the connection. Replace '[website]' with the address of a website you want to test.
   • If the ping is successful, the connection is working correctly.

Troubleshooting

If you encounter issues during the process, check the following:

• Ensure that the modem and server are properly connected.
• Check that the static IP, subnet mask, default gateway, and DNS server addresses are correct.
• Ensure that the software clients are set to obtain their IP addresses and DNS server addresses automatically.
