Nortel Instant Internet 100-S VPN Configuration
This paper will discuss the configuration and use of the Nortel Instant Internet 100-S as a VPN client in our network environment. The Instant Internet 100-S has evolved from the BayStack Instant Internet product. Nortel acquired this product line when it purchased Baynetworks in 1998. A general description of the product can be found in a n article in the Network World publication dated 11-01-1999 (URL below).

HOW-TO Securely Use SNMP on a BGP/MPLS VPN Network
Let us consider the case of an IP/MPLS Service Provider offering extra-net connectivity, along with access to services. The Service Provider manages its MPLS network and in some cases the Customer Edge (CE) routers. The network operations are made possible by its Operations and Business Support System (OSS/BSS) devices, hosted behind some of its own CE routers. Some value may be added by on-demand services hosted behind CE routers on managed servers. All these components can be managed using SNMP; we will see how to make the components interact safely.

IP Security Protocol-based VPNs
IP Security Protocol (IPSec) defines a set of protocols and cryptographic algorithms for creating secure IP traffic sessions between IPSec gateways. Enterprises can no longer keep pace with ever changing technology; legacy networks such as ATM and Frame Relay are examples of such technologies that are not able to keep up with the technological advances. Flexibility, scalability, global reach, and security are critical network components that help to define an enterprise's success. IPSec Virtual Private Networks (VPNs) allow enterprises to leverage the speed, ubiquity, and flexibility of the Internet, while gaining security beyond that which is Provided by legacy network technologies. There have been many improvements in the internet including quality of service, network performance and inexpensive technologies such as DSL. But, one of the most important advances has been in security.

Building a Secure Enterprise Grade VPN
The rising popularity of Virtual Private Networks (VPN) has given birth to a new technology architecture from Cisco Systems that takes these same VPN concepts and encompasses the additional voice and video requirements into a technology called Voice and Video Enabled IPSec VPN or V3PN. This V3PN concept is in fact just a combination of Voice over IP (VoIP) technologies, Quality of Service (QoS) technologies, and Security services into one architectural view. The purpose of this paper is to demonstrate a secure, scalable, and redundant V3PN architecture that can be used as a model for implementation in the Enterprise.

Communicating Through The Tunnel
Information security has emerged as one of the most important segments of the computing industry. Corporations around the world are finding themselves adopting new Internet based approaches to enhance communication and customer satisfaction at reduced costs. Security enables these technologies to be suitable for these organizations because of the advent of authentication, digital certificates, various encryption methods, hardware, and software and network appliances. Theses technologies, along with others are entering the mainstream of business computing, advancing many corporations into the next generation.

Sorting Through the Hype of Ubiquitous Secure Remote Access and SSL VPNs
If I told you that I could give you a car, exactly like the car you already own with the exception that it gets 1,000 miles/gallon and would have no maintenance costs for 10 years, would you start asking me about adding cup-holders? I doubt it-I sure wouldn't. However, if I told you that I could replace your existing remote access solution with one that provides the exact same capability, but has increased deployment flexibility, increased security options, a lower TCO and faster ROI-I am constantly questioned about whether it can provide "ubiquitous" access. The short answer is "No." The real answer is "No. You shouldn't expect it to, don't really want it to and don't really need it."
