The project aimed to create a VPN user on a Cisco 2911 router to allow remote access to an internal network using Cisco VPN client software. The role was to lead and complete the project on time. A VPN client PC was connected to the ISP network using Cisco VPN client software to connect to the VPN on the 2911 router. The router was configured with a dynamic IP address profile and user credentials to authenticate VPN users and assign internal LAN IPs, allowing communication between the VPN client and devices behind the 2911 router without requiring a static external IP.

This document discusses DEAN, a unified controller service that abstracts the controller-specific views of SDN networks and provides a common API. DEAN belongs to the control plane of the SDN ecosystem. It abstracts details of individual controllers and provides a global view of the network and unified services to applications. DEAN currently supports OpenDaylight, Floodlight and ONOS controllers through plugins and provides features like topology information, host information, flow programming and statistics collection through a common REST and RPC API.Name HUB BRIDE ROUTER SWITCH MODEM

This document provides an overview of several networking devices: hub, switch, router, modem, and bridge. It describes each device's function at a high level. Hubs are not intelligent devices and broadcast all data to all connected networks, while switches are intelligent and assign unique MAC addresses. Routers connect different networks and modems convert analog to digital signals or vice versa. Bridges connect two separate networks and act as a bridge between them.Iuwne10 S03 L04

A local area network (LAN) connects computers and devices within a common area through a shared communication line or wireless link to a server. A network connects two or more devices that can communicate, and is comprised of computer systems linked by physical or wireless connections. Switches are active network elements that are faster than hubs, know which devices are connected to their ports, and can be connected to other switches. Routers join multiple networks together by connecting two or more networks and operate at the network layer. The TCP/IP protocol allows different operating systems and networks to communicate using TCP to reliably transfer information and IP to deliver it to the destination computer.Finding An IP Address on Your Network | IP Address Buyer | How to Sell IP Add...

The document discusses the design of a virtual private network (VPN). Key points:
1) A VPN allows hosts scattered across different locations to communicate as if they are on the same local area network by simulating the LAN topology over the Internet.
2) The goal is to design a VPN that provides a generic virtual network interface to allow any network layer protocol (e.g. AppleTalk, IPX) to function, not just IP.
3) The proposed solution uses encapsulation and decapsulation of VPN packets within IP packets to transmit them over the Internet. A "shim header" is added to direct packets to the correct destination VPN client.7256 ccna security_chapter_8_vpn_dl3_oz_20130409031455

Here are the key steps to configure an IPsec VPN using CLI:
1. Configure ISAKMP policy for IKE phase 1 negotiation.
2. Define IPsec transform sets for encryption and authentication algorithms.
3. Create crypto access control lists (ACLs) to define which traffic should be protected.
4. Apply a crypto map to the interface to associate the ACLs and transform sets to establish security associations for IPsec.
This summarizes the major configuration tasks for setting up an IPsec VPN using CLI on Cisco devices. The steps establish the IKE and IPsec policies, define what traffic to protect, and apply it to interfaces.CCNA Security - Chapter 8

The document discusses VPN types and protocols. There are two main VPN types - remote access VPN which allows remote users to access a private network, and site-to-site VPN which connects different company sites. Common VPN protocols described include IPSec, L2TP, PPTP, MPLS VPN, SSTP, and IKEv2. Each protocol provides a different level of security for VPN connections.Katuwal_Arun_flex_get_vpn.pdf

This document is a 36-page thesis written by Arun Katuwal for a Bachelor's Degree in Information Technology from Metropolia University of Applied Sciences. The thesis studied the configuration and deployment of IKEv2, FlexVPN, and GET VPN technologies. It included designing a network topology to test IKEv2 and FlexVPN in a school laboratory. Cisco routers were configured to establish site-to-site FlexVPN tunnels between two networks. The connections were tested and performed as designed. The thesis provided details on VPN technologies, IKEv2, FlexVPN architecture and configuration, and GET VPN architecture to allow readers to evaluate the comparison between these VPN solutions.A Mobility Scheme For Personal And Terminal Mobility
A Mobility Scheme For Personal And Terminal MobilityMonica Waters

This document proposes a mobility protocol called the Terminal Mobility Support Protocol (TMSP) that enables both personal and terminal mobility for IP-based applications. TMSP uses an IP-to-IP address mapping module at the network layer and a user agent to manage changes in a mobile node's IP address without requiring a permanent IP address, home server, or network support. The protocol was implemented on Linux and experimental results show it can support UDP and TCP connections for applications like VoIP and video conferencing as a mobile node roams across wireless networks without packet loss or affecting throughput.V P N

The document summarizes virtual private networks (VPNs), including their definition, need, and how they work. VPNs allow corporate networks to securely transmit data over the public internet. They provide flexibility, scalability, and cost savings compared to traditional private networks. The document describes various VPN types and protocols like IPsec and PPTP. It also discusses VPN hardware and software requirements and advantages/disadvantages of VPNs.Ip tunnelling and_vpn

A virtual private network gives secure access to LAN resources over a shared network infrastructure such as the internet. It can be conceptualized as creating a tunnel from one location to another, with Encrypted data traveling through the tunnel before being decrypted at its destination.

Cisco Packet Tracer is a network simulation program that allows students to experiment with network behavior. The document describes how to set up three example networks using Packet Tracer. It explains how to connect routers and PCs, assign IP addresses to devices, and configure routing protocols to allow communication between the networks. Setting up the example networks demonstrates how to build and test a multi-network topology in Packet Tracer.ITERA Paper - IPSec L2TP Vulnerability

1) The document describes a vulnerability in IPSec/L2TP VPN connections where filtering UDP port 500 to drop IKEv2 negotiation packets allows an insecure L2TP connection to still be established, compromising confidentiality.
2) A simulation was created using 3 VMs to demonstrate exploiting this by capturing plain text traffic.
3) The only current workaround is changing the Windows VPN encryption setting, but a patch is needed to fully address the vulnerability.CV-Gunawan Pujasandi

This module covers VPN and IPsec concepts, including how VPNs use encryption protocols like IPsec to securely connect site-to-site and remote networks. It describes different types of VPNs for remote access and connecting sites, as well as how the IPsec framework provides confidentiality, integrity, authentication, and secure key exchange to protect network traffic. The module also examines IPsec encapsulation modes and the benefits of dynamic VPN solutions like DMVPN and IPsec VTIs.SplitVPN
- 1. Project Details Name: SPLIT IPSEC VPN Aim: Creating a VPN user on Cisco 2911 router to access its internal network from outside using Cisco VPN client Software. Role: Led / owned the project from front and completed it on time with required output. Topology: Description: VPN client can be connected to any network regardless of the Static IP with his provider. As we are not doing a Site – Site VPN wherein the router on other side requires Static IP to establish full tunnel. I have connected VPN Client PC on the ISP side network using Cisco VPN Client software to connect to VPN. On VPN Router (2911) I created a dynamic IP Address profile for the VPN users along with the user credentials to authenticate. Router once accepted it will assign the LAN IP’s to the VPN Client and it can communicate with the other party sitting behind 2911 router. VPN Client doesn’t get the static IP from 2911 Router. Every time the VPN goes down and re-connect it will assign new IP to it.
