Windows HTTP IP Filter Example

I have used this tip when troubleshooting, configuring external firewalls, and baselining.

It's quite straightforward; I block specific IP addresses, port numbers, or services to test a theory before suggesting configuration changes.

In this specific example, I use my portable hfs webserver (https://www.rejetto.com/hfs/) application to test the filter and show you how to block an IP address.

The Challenges of Packet Captures

 

NetAlly asked me to work with them on some network troubleshooting articles/videos.

Of course, I suggested and started with packet captures since that is always a hot topic.

Here is an excerpt from the first one:

"Packet analysis is difficult enough without having to worry about the GIGO (Garbage In, Garbage Out) effect. Capturing the right spot, with the correct settings, makes all the difference in the world.

In this series, Tony Fortunato of the Technology Firm will cover various tips, tricks, and settings to keep in mind when capturing packets."

Azure Networking Costs: A Practical Guide (Gilad David Maayan)

 

Azure networking refers to the network infrastructure and services provided by Microsoft Azure, a cloud computing platform. It enables organizations to connect their resources and workloads within the Azure environment and extend their on-premises networks to the cloud. Azure networking encompasses various services such as virtual networks, load balancers, virtual private networks (VPNs), and Azure ExpressRoute. In this article, we’ll review the costs of networking services and how to reduce them to optimize overall Azure costs.

Create a Wireshark Desktop Shortcut To Automatically Capture

Here's how to create a windows desktop shortcut to automatically start capturing when you launch the Wireshark GUI.

Quick Peek at Cports

Cports, or Currports is a really helpful portable Windows application from www.Nirsoft.net that displays your services, local/remote ip addresses, port numbers and a lot of other stuff.

I have used this application when I wasn’t able to capture packets and found the ‘netstat’ command too tedious. The filtering feature is something I wanted to focus on since it’s a real time saver.

Have fun and let me know if you want to see more ‘free applications’.
