Splunk allows you to monitor, search, and analyze machine-generated data in real-time. It captures and indexes the data in a searchable container and produces graphs, alerts, dashboards, and visualizations. This guide explains how to port forward Splunk.

Requirements to Port Forward Splunk

Just before you begin with the process of port forwarding, make sure you have the following things:

  • Downloaded and installed the Splunk server.
  • The IP address of your router.
  • The IP address of your device.

TCP and UDP ports of Splunk for your device as mentioned in the section below.

Step-by-step guide on how to port forward Splunk

Now that you have the above details noted down, you can move to the next stage of Splunk port forwarding:

  1. On your web browser address bar, type your router’s IP Address/Default Gateway.
  2. Log in with your router’s credentials (username and password) to view your router’s firmware settings.
  3. Navigate to the port forwarding section of your router.
  4. Click on Port Forwarding.
  5. Enter the IP address of your device in your router in the correct box.
  6. Put the TCP and UDP ports of the Splunk server in the boxes in your router. The default Splunk port number is 8089. And then click the apply button.
  7. And you’re done. Restart your router to let the changes take effect.
  8. Once your changes take effect, now you can host a Splunk server and let your friends connect to it as well. To let them connect to it, you need to provide them with the hostname you are using, along with the port number. For example, ‘hostname.domain.com:25565’.

How to open ports behind CGNAT

What if your ISP performs CGNAT? Most ISPs perform CGNAT (Carrier-grade Network Address Translation) to conserve bandwidth and assign a single IP address to multiple users connected to the same internet network. However, CGNAT makes it difficult for you to open ports on the router. 

To get around the CGNAT issue, you can use the Port Forwarding add-on to bypass this problem and port forward routers without hassle. 
Here’s more information on how to use PureVPN’s Port Forwarding add-on and bypass CGNAT in a few clicks.

PureVPN’s Port Forwarding Add-on

A secure way to open all ports

To most people, port forwarding is quite a demanding task. For starters, every router has a different console, which often makes it difficult to navigate to specific settings.

Secondly, you won’t always be able to open Splunk ports on your router if your ISP restricts the ports. Yes, you heard that right! ISPs are notorious for blocking ports due to security reasons. If ISP isn’t the reason behind a blocked port, then perhaps it could be your operating system’s firewall.

Well, you can eliminate all these problems on all your desired systems with PureVPN’s Port Forwarding add-on. Through the Port Forwarding add-on, you can allow all ports, disallow all ports, and allow specific ports.

Frequently Asked Questions

Is Splunk TCP or UDP?

Use the TCP protocol to transmit data from any external host to your Splunk Enterprise server. The Splunk Enterprise can index remote data from any application that sends information over TCP. Interestingly, both Splunk Enterprise and the universal forwarder support monitoring over UDP.

Is port forwarding a good idea?

Port forwarding is a great method of keeping public IP addresses safe. By doing so, it can safeguard servers and clients from unapproved access, as well as “hide” the services and servers available on a network. Additionally, port forwarding limits accessibility to and from a network.
