🚀 Network Design with GNS3 and pfSense 🚀 Building and understanding complex network environments is key to both securing and hacking networks. Using GNS3 and pfSense , a virtual network was constructed, complete with segmented traffic, secure routing, and multiple connected devices. Configuration: - pfSense was configured to handle LAN and WAN traffic, implementing routing, firewall policies, and traffic filtering. - Virtual PCs with static IPs were connected via switches, routed through the pfSense gateway. - Network connectivity and communication were validated through ping tests, ensuring devices interact as expected. Understanding how to configure and secure networks is essential for anyone involved in ethical hacking. The better the grasp on network architecture, the better the chances of identifying vulnerabilities and exploiting them. #Networking

Returning to experiments in @gns3 after a year and omg I forgot how amazing it is! The task now is to model future network in the hosting collocation (moving away from Hetzner dedicated servers). GNS3 Mikrotik's RouterOS VHDs = ❤️.

Still no update from @teachable as their support refuses to recognize the problem allowing us to PAY THEM to get the system up and running. Attached is the error message we keep getting 👇👇 An error occurred while processing your card. Please refresh the page and try again.

Further update here. @teachable support has been terrible in helping to find a resolution and refuse to bring us back online. We are going to be looking to migrate off the platform as its disappointing with 100,000 learners that we are getting treated like this.

Still no resolution from the @teachable. @ankurnagpal - know you are long done from the organization but we were one of the 1st customers of Teachable and we cannot get ahold of a single person to help us get our site back. Any contacts you can share?
