Connecting remote offices or home PC’s to the Internet and corporate networks can be troublesome, requiring a balance of bandwidth limitations, security concerns and firewall functionality. Simple setup is also a necessity, so less-experienced users can easily get these fairly complex systems up and running. In addition, the cost of communication hardware and software must be kept to a minimum to meet tight budgets.
The routers also offer firewall protection for security, productivity and operational purposes. Though these aren't heavy-duty firewalls like those that cost upwards of $10,000, they do offer the most common protocol-filtering mechanisms.
All three routers offer browser-based installation and management, and operate as Dynamic Host Configuration Protocol (DHCP) servers. This feature automatically supplies the workstation with an IP address and gateway setup information upon booting-eliminating the arduous task of manually assigning IP parameters to workstations during setup.
Most of the devices support the same protocols: TCP/IP; Point-to-Point Protocol (PPP); HTTP; Challenge Handshake Authentication Protocol (CHAP); Password Authentication Protocol (PAP) and Network Address Translator (NAT). These protocols allow users to connect to any standards-compliant ISP (via PPP) and authenticate using either CHAP or PAP authentication protocols. Once connected, these routers can share a single IP address among many workstations using the NAT protocol, saving the cost of extra IP addresses.
However, each router was different in very important ways that you must consider before buying.
Ramp Networks WebRamp 310i
I had this router up and running within minutes, and configuring five workstations took little more effort than simply powering them up. It allowed me to easily configure all attributes, from ISP information to security, using a Web browser. The WebRamp offers NAT, Virtual Private Network (VPN) tunneling via Point-to-Point Tunneling Protocol (PPTP), and packet filtering based on protocol and port number.
It was the only router to support the IPX protocol, allowing the workgroup to access NetWare servers when connecting directly to the corporate office. Another unique feature is the WebRamp 310i's POTS interface, which allows data calls to be pre-empted on incoming or outgoing telephone voice calls. This enables workgroup members to use the same phone lines as the router and save on the cost of extra phone lines.
The router is equipped with two built-in 56K V.90 modems and has an external 230Kb per second RS-232 port. The WebRamp 310i's 47.59Kbps performance put it slightly behind the ProxyServer's 49.83Kbps throughput. The router has a built-in four-port 10BaseT hub for building an instant Ethernet network.
In order to protect the application servers from the internet, the most common un-trusted network, the proposal suggests a firewall to be installed between the internal network and external router. The firewall would be an Adaptive Security Appliance (ASA) firewall, "the ASA is not just a pure hardware firewall. In brief, the Cisco ASA is a security device that combines firewall, antivirus, intrusion prevention, and virtual private network (VPN) capabilities. It provides proactive
... access to what and in which sequence. The router connects the LAN to other networks, which could be the Internet or another corporate network so that the LAN can exchange information with networks external to it. The most common LAN operating systems are Windows, Linux, and Novell. Each of these network operating systems supports TCP/IP as their default networking protocol. Ethernet is the dominant LAN standard at the physical network level, specifying the physical medium to carry signals between computers, access control rules, and a standardized set of bits used to carry data over the system. Originally, Ethernet supported a data transfer rate of 10 megabits per second (Mbps). Newer versions, such as Fast Ethernet and Gigabit Ethernet, support data transfer rates of 100 Mbps and 1 gigabits per second (Gbps), respectively, and are used in network backbones.
Security of the companies data is one of the most important components which allows the business to perform its day to day operation using various networking devices, services that absolutely needs to be protected from intruders. Some of these devices include online transactions, the exchange of data between users and clients both internal and external and external web data needs to be secured. There are several polices that would need to be configured such as a web sever and firewall configurations. However, with these configurations the first and most important task is to identify any vulnerabilities or loopholes in security within the company. The company has both LAN (Local Area Network) and WAN (Wireless Local Area Network) and a web sever. These resources need to be secured at all times from hackers or anyone else by implementing the appropriate security measures.
The Unistep IRP Elexol EtherIO 24 Module is a network board that is integrated with features that allow multiple devices over the same network to communicate. This microcontroller was designed to be implemented as an addition to a larger network system; the multiple features and capabilities allow for various industrial and home applications. Ethernet is very common and used in most networks, which makes the IRP a great candidate for networking problems both at home and in the work field.
It works with the border router to filter information trying to enter or leave the organization.
Another benefit of an online portal is that users can work from home or from satellite offices as needed. For the sake of redundancy, it may be prudent to keep the Virtual Private Network (VPN) connection to our satellite office; however, it would not be necessary. It would also be wise to remove the RAS and PBX from the company network. These legacy systems allow remote dial-up users to authenticate to the network, but their functionality could be accomplished through a web browser under the new system.
Virtual Private Network presents some advantages over the traditional network technologies. VPN offers direct cost savings over leased lines or long-distance calls for remote access, savings resulting from reduced training requirements and equipment, increased flexibility, scalability, and security. The main advantage of VPN is the cost savings of Internet VPN when compared to networks built using conventional leased lines. Leased lines include tariffs that have an installation fee, a fixed monthly cost, and a mileage charge. The cost to an organization of traditional leased lines may be reasonable at first but can increase exponentially as the organization grows. As an organization grows and more companies must be added to the network, the number of leased lines required increases dramatically. VPN that utilizes the Internet avoids this problem by simply tapping into the geographically distributed access already available. Another way VPN reduces costs is by reducing the need for long-distance telephone charges for remote access. Instead of having the offsite team of a company dial into the corporate modem bank via long distance lines, the company’s VPN allows them to simply place local calls to the ISP’s POP in order to connect to the corporate network.
The components are the SIP enabled enterprise edge device and PBX, internet telephony provider and the public switched telephone network or PSTN. The PBX is usually IP based and communicates with the endpoints over the same IP network. It is located in the central office of
This proposal is for a small office that will have users who are connected by Wi-Fi or cable. The network will include devices and resources that is shared among all the users. The network will need to have security measures in place to protect the entire network and keep the wireless access secure and available only to employees of the company.
SLIP and PPP are two communication protocols which allow a computer connected to a server via a serial line (such as a modem) to become an actual node on the internet. This allows you to run network applications on your home computer directly. While SLIP and PPP are largely similar, there are some key differences. PPP is a newer protocol, better designed, and more acceptable to the sort of people who like to standardize protocol specifications.
A network is merely a series of interrelated components, sharing information, linked by one common lifeline, spanning across a large area. When most people think of networks in the computer sense, cyberspace and the internet are usually types of networks that come to mind. However, these are just small pieces that complete the network puzzle. Many other types of networks include Local Area Networks (LANs), Wide Area Networks (WANs), and also wireless networks as well. This paper will provide some insight into the development, objectives, and impact of various network systems.
For the most part we have addresses the needs of our sales force on a case by case basis but going forward we really need to ensure we have a defined policy to streamline remote access. To accomplish this there are a few benchmarks we need to achieve. First of all the network has to be reliable or in more technical terms it needs to have high availability. Most importantly we need to make sure that the network is secure as much as it is possible with all the different types of users asking for access. Lastly, we need to address how we handle employees using personal or non-company issued computers and how we ensure that those machines meet of other remote access policies.
Woodworking is not just a profession. It is an art; an art of making furniture and other things out of wood. Chairs, cupboards, and cabinets, all are results of woodworking. Some people actually adopt woodworking as a hobby, which even becomes their profession later in their life. However for accomplishing woodworking, you need to use a variety of tools.
Local Area Networks also called LANs have been a major player in industrialization of computers. In the past 20 or so years the worlds industry has be invaded with new computer technology. It has made such an impact on the way we do business that it has become essential with an ever-growing need for improvement. LANs give an employer the ability to share information between computers with a simple relatively inexpensive system of network cards and software. It also lets the user or users share hardware such as Printers and scanners. The speed of access between the computers is lighting fast because the data has a short distance to cover. In most cases a LAN only occupies one or a group of buildings located next to each other. For larger area need there are several other types of networks such as the Internet.
A firewall is a network device, hardware, software, or a combination of the two, whose purpose is to enforce a security policy across its connections. It is comparable to a wall that has a window where the wall serves to keep things out, except those permitted through the window. A security policy acts like the glass in the window; it permits some things to pass, light, while blocking others, air. The heart of a firewall is the security policy that it enforces.
