Access VPN Design

Access VPN will leverage the availability and low cost of the Internet to connect corporate headquarters through WiFi, DSL and wired access circuits provided by local Internet service providers. The main problem is that when moving from a remote laptop to a corporate headquarters over the Internet, the company’s data must be protected. A client-initiated model will be used that creates an IPSec tunnel from each client laptop that ends with a VPN concentrator.

Each laptop will be configured with VPN client software, which will run on Windows. The teleworker must first dial the local access number and authenticate with the ISP. The RADIUS server will authenticate each dial-up connection as an authorized remote worker. Once the operation is complete, the remote user will authenticate and authenticate on the Windows, Solaris, or Mainframe server before launching the application. Two VPN concentrators will be configured for Virtual Routing Redundancy Protocol (VRRP) failover to prevent one of them from being unavailable.

Each hub is connected between an external router and a firewall. The new features of the VPN Concentrator prevent denial of service (DOS) attacks from external hackers that may affect network availability (Canada vpn). The firewall is configured to allow source and destination IP addresses that are assigned to each remote worker from a predefined range. In addition, any protocol and application ports will be allowed to traverse the required firewall.

VPN Design Extranet

The VPN Extranet is designed to allow secure connections between each partner office and the corporate headquarters. The primary goal is security because the Internet will be used to carry all data traffic for each partner. Each trading partner will have a circuit connection that will eventually enter the VPN router at the corporate headquarters. Each partner in the switch and its VPN router will use a router with a VPN module.

This module provides IPSec hardware encryption and high-speed packets before being transmitted over the Internet. In the case where one of the links is unavailable, the VPN router peer of the corporate central office has dual links to different multilayer switches for link diversity. It is important that traffic from one business partner does not end up in the office of another business partner.

These switches are located between external and internal security servers and are used to connect to public servers and external DNS servers. This is not a security issue because external firewalls filter public Internet traffic.

In addition, filtering can be implemented in each network (Canada vpn) switch to prevent advertised routing or exploits from connecting to business partners in the multilayer switch at the corporate headquarters. A separate VLAN is assigned to each partner on each network switch to improve the security and segmentation of subnet traffic. A Level 2 external firewall will check each packet and allow those packets with the original and target IP of the trading partner, the application and the required protocol port. The partner session must authenticate to the RADIUS server. Once complete, they will authenticate to the Windows, Solaris or Mainframe host before launching the application.
