What's VPN? VPN(Virtual Private Network)technology included in Windows Server 2003 helps enable cost-effective, secure remote access to private networks. VPN allows administrators to take advantage of the Internet to help provide the functionality and security of private WAN connections at a lower cost. In Windows Server 2003, VPN is enabled using the Routing and Remote Access service. VPN is part of a comprehensive network access solution that includes support for authentication and authorization services, and advanced network security technologies.
There are two main strategies that help provide secure connectivity between private networks and enabling network access for remote users.
Dial-up or leased line connections
A dial-up or leased line connection creates a physical connection to a port on a remote access server on a private network. However, using dial-up or leased lines to provide network access is expensive when compared to the cost of providing network access using a VPN connection.
VPN connections
VPN connections use either Point-to-Point Tunneling Protocol (PPTP) or Layer Two Tunneling Protocol/Internet Protocol security (L2TP/IPSec) over an intermediate network, such as the Internet. By using the Internet as a connection medium, VPN saves the cost of long-distance phone service and hardware costs associated with using dial-up or leased line connections. A VPN solution includes advanced security technologies such as data encryption, authentication, authorization, and Network Access Quarantine Control.
Note *Network Access Quarantine Control is used to delay remote access to a private network until the configuration of the remote access computer has been examined and validated.
Using VPN, administrators can connect remote or mobile workers (VPN clients) to private networks. Remote users can work as if their computers are physically connected to the network. To accomplish this, VPN clients can use a Connection Manager profile to initiate a connection to a VPN server. The VPN server can communicate with an Internet Authentication Service (IAS) server to authenticate and authorize a user session and maintain the connection until it is terminated by the VPN client or by the VPN server. All services typically available to a LAN-connected client (including file and print sharing, Web server access, and messaging) are enabled by VPN.
VPN clients can use standard tools to access resources. For example, clients can use Windows Explorer to make drive connections and to connect to printers. Connections are persistent: Users do not need to reconnect to network resources during their VPN sessions. Because drive letters and universal naming convention (UNC) names are fully supported by VPN, most commercial and custom applications work without modification.
VPN Scenarios
Virtual private networks are point-to-point connections across a private or public network such as the Internet. A VPN client uses special TCP/IP-based protocols, called tunneling protocols, to make a virtual call to a virtual port on a VPN server. In a typical VPN deployment, a client initiates a virtual point-to-point connection to a remote access server over the Internet. The remote access server answers the call, authenticates the caller, and transfers data between the VPN client and the organization’s private network.
To emulate a point-to-point link, data is encapsulated, or wrapped, with a header. The header provides routing information that enables the data to traverse the shared or public network to reach its endpoint. To emulate a private link, the data being sent is encrypted for confidentiality. Packets that are intercepted on the shared or public network are indecipherable without the encryption keys. The link in which the private data is encapsulated and encrypted is known as a VPN connection.
Remote Access VPN
Remote access VPN connections enable users working at home or on the road to access a server on a private network using the infrastructure provided by a public network, such as the Internet. From the user’s perspective, the VPN is a point-to-point connection between the computer (the VPN client) and an organization’s server. The exact infrastructure of the shared or public network is irrelevant because it appears logically as if the data is sent over a dedicated private link.
Site-to-Site VPN
Site-to-site VPN connections (also known as router-to-router VPN connections) enable organizations to have routed connections between separate offices or with other organizations over a public network while helping to maintain secure communications. A routed VPN connection across the Internet logically operates as a dedicated WAN link. When networks are connected over the Internet, as shown in the following figure, a router forwards packets to another router across a VPN connection. To the routers, the VPN connection operates as a data-link layer link.
A site-to-site VPN connection connects two portions of a private network. The VPN server provides a routed connection to the network to which the VPN server is attached. The calling router (the VPN client) authenticates itself to the answering router (the VPN server), and, for mutual authentication, the answering router authenticates itself to the calling router. In a site-to site VPN connection, the packets sent from either router across the VPN connection typically do not originate at the routers.

Windows 7 wireless, setting up, defining features of this network will be the lack of network passwords for local connections(both wirelessly or wired) and no single “boss” computer. Devices on the network will act as peers – no computer will rely on another computer to be present on the network – in order to reach the Internet, but it won’t be an ad-hoc network. File and folder sharing, of course, will depend on other computers being present, but we’ll look at specifying what folders we’ll share with others and these we will share and share alike.Router Configurations
The most boss-like object in the network is the wireless router. For our purposes, we’ll presuppose that each computer can connect to the router. In our test network, the Vista desktop computer has the wired connection to the router and was used to set the router up. It’s very important that the router is not left at defaults and is set up properly because the security of the simplified network is based on the router and on having both a strong network password and an encrypted connection. By strong password, we mean a mix of letters and numbers that can’t be guessed or easily “cracked” by brute force. Your router setup program may suggest a pseudo-random password based on the encryption you selected. This is very safe to use. By encryption, we mean Wi-Fi Protected Access, or WPA-PSK. The “PSK” part stands for “pre-shared key,” which is that secure password.
Since setup varies and you’ll need to use the documentation for your router to perform it, we’ll only briefly touch further on this. You want to set it to broadcast your network name or service set identifier (SSID). You’ll want to make sure that each computer on the network can reach the Internet. A somewhat common problem you may encounter is that a PC can connect wirelessly to the router and seems to be passing some data when you view “Status” for the device, but the web browser can’t reach any web pages.
This can mean that the computer was set up by default for wireless networking(with Microsoft networks, of course), but not for Internet access. It is, however, easy to fix.

Backlink berkualitas tentunya sangat dibutuhkan untuk meningkatkan pagerank, semua orang sudah tahu. Apalagi bagi para blogger yang terjun dalam bisnis paid review yang memang menggunakan pagerank sebagai syarat wajib untuk menuju kesuksesan. Tidak panjang lebar, karena backlink dan pagerank sudah saya bahas sebelumnya. Saya hanya akan menjelaskan sedikit apa yang saya tahu dan tentunya semuanya berdasarkan pendapat saya sendiri. Pertama - tama, kita harus tahu, apakah backlink berkualitas itu? kenapa banyak orang rela mengeluarkan banyak uang hanya untuk mendapatkan backlink berkualitas tersebut? Apakah untuk menaikkan PR atau cuma untuk menaikkan hasil tertinggi di SERP seperti yang dilakukan oleh para kontestan SEO dalam memperebutkan posisi atas. Karena kalau kita ketahui ternyata ada perbedaan diantara keduanya.
Backlink untuk meningkatkan pagerank
Untuk kita blogger pemula, backlink yang berkualitas mempunyai tujuan untuk meningkatkan pagerank google. Kalau ini yang kita cari tentunya backlink yang bagus dan berkualitas adalah backlink dari blog atau website yang mempunyai pagerank tinggi. Begini gambarannya, dibandingkan backlink dari blog PR1 sebanyak 6 kali dengan blog PR6 sebanyak 1 kali, masih bagus yang PR6. Dengan harapan website kita akan ikut terangkat pagerank-nya. Lalu, Bagaimana cara mendapatkan backlink tersebut? Tentu banyak cara yang salah satunya adalah berkomentar di blog dofolow dengan meningalkan link kita. Kalau kita hanya ingin menaikkan Pagerank, kita tidak usah memandang blog inggris ataupun indonesia. Asal mendapat backlink dengan page rank tinggi maka blog kita juga akan semakin naik page rank-nya.
Backlink untuk SERP
jika mencari backlink berkualitas dengan tujuan mendapatkan posisi atas di SERP. Mungkin bisa dikatakan banyak sekali perbedaan. Tapi saya akan memberikan perbedaan tersebut sesuai yang saya ketahui. Kalau untuk menaikkan PR kita membutuhkan backlink dengan PR tinggi, walaupun cuma sedikit, maka untuk menaikkan SERP kebalikannya. Walaupun PR kecil tapi banyak, maka posisi SERP akan lebih bagus dibanding PR tinggi tapi sedikit. Dan juga target mesin pencari harus kita perhatikan. Kalau masalah menaikkan PR tadi kita tidak peduli walaupun itu blog ingris atau indonesia dan lainnya. Tapi kalau SERP, jika target kita google indonesia, maka usahakan mencari backlink dari blog indonesia juga. Jika target adalah blog inggris, maka usahakan backlink dari blog berbahasa inggris. Namun, akan lebih baik jika kita juga melihat kualitas backlink kita.
Selamat mencoba, tutorial ini saya dapat berdasarkan pengalaman saya sebagai SEO pemula, get more and more quality backlink.
Website are the basic tools for us to share on the internet, especially for online promotion. Links from the inside (called internal links) of your site will get you to the top of search engine rankings, but if internal linking isn’t getting you where you need to go, then it’s time to bring in some help from outside of your site. Over time, your link building efforts will increase your ability to do things with internal links as well.Please remember, link building is the only method to increase our website search engine ranking. If we can do link building well, we have done the right online promotion method. With each planning cycle, take stock of your links, and the effectiveness of your link building activities. Activities that have been particularly successful are worth pursuing further or expanding. Those that haven’t delivered need to be improved or removed from your plan.
Because I put a strong emphasis on profitable promotions, I like to try something new with every planning cycle. I always want to have at least one new type of promotion going on, with the goal in mind of creating a profitable marketing activity that will create links as a side benefit.
If you have paid for advertising from vertical directories, take a look at the traffic these links are bringing in, and how well it converts into leads and sales. If you find a particularly profitable type of advertising, then look for ways to expand it, possibly reducing the budget in other areas where you aren’t generating a profit.
In the long run, we want our link building campaign to pay for itself. That’s not an easy goal to reach right away, but it is possible to get there over time. So, don;t think the other way with our online promotion method, just focus for the link building campaign.
SEO are the most important thing when we have a site, one of the worst mistakes that novices make is trying to focus on a single word or phrase for SEO keyword, and attempt to build a good website that will rank well. Extremely general terms such as these are very competitive, difficult for search engines to handle well (in terms of giving good results to searchers), and hardly worth the trouble in the first place.Let’s imagine that, after spending hundreds of hours tweaking, perfecting, and promoting your site, you managed to get a #1 ranking for “real estate.” Unless you sell real estate of all kinds in every part of the world, a substantial amount of the traffic you’ll get will come from people who are looking for something you don’t have to offer.
Although you may not optimize your site for such keywords. SEO keyword learning is very important that you know what they are, as it applies to your site. As you work through this post, make a list of the 5-10 “major” keywords that describe your website. It's named SEO keyword learning.
