Access Laptop Weblogic From External Network

Question

I have installed Weblogic Server version 12.1.3 on my laptop. From the laptop locally, I can access it via http://laptop_name:7001/console. However, from an external network, this is not accessible. The laptop connects to my network via a Huawei HG8245Q make and model router.

Question: What are the steps required to configure the Weblogic server to use an external IP or machine name so that I can access it from an outside network?

Answer 1

On the router or firewall of the network the laptop_name is connected, you configure it to forward incoming traffic from the Internet/WAN going to TCP port 7001 to the local IP address and port of the laptop_name machine. This functionality within the router or firewall device may be called port forwarding or sometimes it is referred to as virtual server.

Essentially though it can be configured to forward inbound traffic from an ISP router's or firewall appliance's external/WAN/untrusted interface on a specific port to go to the local/private IP address and port of the machine running the Weblogic server.

Since you mention the router is of the Huawei HG8245Q make and model, according to the "Fastest Way to Forward Ports on the Huawei HG8245 Router" you configure this by following this process:

To open a port for the Huawei HG8245 router you need to:

1. Setup a static IP address on the device or computer you plan on forwarding the ports to.

2. Login to your Huawei HG8245 router.

3. Find the port forwarding section.

   • Click the Forward Rules link.
   • Click on Port Mapping Configuration.

4. Create a port forward entry or rule.

Note: If you are only forwarding a single port then you can enter that same port number into the External Start Port, External End Port, Internal Start Port and Internal End Port boxes. If you are forwarding a range of ports then you need to enter the lowest number of the range into the External Start Port and Internal Start Port boxes and the highest number of the range into the External End Port and Internal End Port boxes.

Important: So this means per the above Note section, you will put 7001 into those fields.

Server Exposure Security

If the Weblogic server has any vulnerabilities, when you set this up, you are essentially making it accessible to anyone from the Internet. So you are exposing this server to the outside world so think about this and use caution and/or security best practices accordingly as well with your environment and configuration.
