[Solved] Connect GNS3 to Internet via Host Wi-Fi, Ethernet Adapter

Hi there, in my last articles we had covered Interfacing of GNS3 router to physical computer and Connect GNS3 to VirtualBox. Today I’m gonna to describe the sequential procedure to connect GNS3 to internet over host Wi-Fi adapter and over Ethernet adapter. There are many virtual networking tutorials available in the internet explaining the same. But all those describes with reference to Ethernet adapter. So I’m planning to connect GNS3 to internet via Wireless NIC adapter as well as Ethernet adapter. If you connect GNS3 router to internet over wireless […]

[Solved] How to Connect GNS3 to VirtualBox: Virtual Network Lab with GNS3

We were discussing about physical networking with GNS3. GNS3 is the wonderful software for virtual networking computing. Last article, we had a discussion on virtual LAN network by interfacing GNS3 to local PC via Microsoft Loopback adapter. In this tutorial I would like to share how to configure GNS3 to connect VirtualBox virtual machines. As we know GNS3, the best virtual network software, supports oracle VirtualBox, hence it is easy to work around VirtualBox virtual machines (VMs) as comparing to vmWare VMs. Even though we could Interface GNS3 to vmWare with […]

How to Calculate Idle PC Value in GNS3 Network Simulator 0.8.6?

GNS3 (Graphical Network Simulator) is the best open source Network simulator that can be used while setting up a computer network. GNS3 works by consuming real Cisco IOS images which are emulated using a program called Dynamips. Hence it provides real time experience to the user and serves many of the network engineers today to design and collaborate their networks. Using GNS3 you can design and experiment multiple networks without having any dedicated network hardware. The key feature of this router simulator is that you will be able to connect […]

Cisco Standard Named Access Control List configuration

Hi, welcome to another episode of Cisco networking tutorial. We were discussing with network security focused on Access Lists. We did some labs related to Standard Numbered ACL and Extended Numbered ACL. Today I would like to show you Cisco Standard Named Access Control List configuration. Cisco standard named access-list overcomes the limitations of Numbered Access Control list. As we know Named ACL further divided in to Standard and Extended. Numbered ACL is addressed by a Number whereas Named ACL referenced with a NAME. Named ACL provides more flexibility for […]
