Routed Mode WanLinks with Virtual Routers

Goal: Setup a Routed Mode WanLink between two Virtual Routers.

In this test scenario, LANforge-ICE is used to simulate a routed network where incoming traffic on one port is sent through one Virtual Router then through a WanLink, then through a second Virtual Router and then finally out to a port on a different network.

Check if rogue DNSChanger has changed your DNS settings

Domain Name System or the DNS system is an Internet service that converts domain names into numerical Internet protocol (IP) addresses. These numerical IP addresses are used by computers to connect with each other.

When you type a domain name in the address bar of your browser, your computer contacts DNS servers. It then finds out the IP address for that website. Once this is done, your computer then uses this IP address to connect to the website.

Manage web browsing speed by changing DNS settings

DNS or Domain Name System, helps resolve the name of any web address. When you type a domain name in your browsers address bar, say www.TheWindowsClub.com, your computer resolves this name into the IP address of the Internet server, where the site is hosted, using the Internet Protocol.

The Windows operating system, is set by default, to automatically use the DNS server of your ISP or Internet Service Provider.

A slow DNS server could be one cause for poor web browsing speed. If your ISP’s DNS server is slow, or responds slowly, or at times is overloaded, it may cause an additional delay of a few seconds, every time you go on to load a new web page.

While is most cases, keeping the default option is a good idea, if you find that your default DNS provider is slow, you may want to consider finding one that is fast. To test the response time for your DNS server, you can use Dig. It is important to know that what may be good for one person in one part of the world may not necessarily be good for another person sitting in another part of the world.

How to change DNS settings in Windows 7 | 8

Most are aware that Google Public DNS has been recently launched. If you wish, you can override the default DNS (Domain Name Server) settings on your computer so you can specify which DNS server is used, or which IP address should be used for a particular domain.

Manage Different Profiles with Pre-configured IP Settings Using TCP/IP Manager

There are some really good programs that make managing different set of profiles with pre-configured IP settings a breeze. TCP/IP Manager is one amongst them. The program has the ability to manage up to 10 different profiles with individual TCP/IP settings and no matter where you are, at home or at work it tracks network configuration at various locations.

TCP/IP Manager can be downloaded for free and consumes less than 500KB of your hard disk space. It is an open-source tool that makes changing network settings a one-click operation.

You all will agree that it is not only tiring but a time-consuming task to manually change the TCP/IP network settings every time you switch to a different environment. Say you are in your office then switching to your office network from home network may require different DNS setting. Moreover, you will have to type/enter the IP address, Subnet mask, default gateway and DSN one by one thereby wasting your time and energy.

So, why not have a utility that simply allows users to copy and paste the respective network IP addresses directly and eliminate the need of re-typing unnecessarily? And TCP/IP Manager does exactly this! Besides, it also provides the option to choose specific profile and minimize it to the system tray so that it can be accessed later whenever required by simply clicking on the system tray icon.

What are DNS and the DNS Proxy?

The DNS (domain name system) is a network system of servers that translates numeric IP addresses into readable, hierarchical Internet addresses, and vice versa. This is what allows your computer network to understand that you want to reach the server at 192.168.100.1 (for example) when you type into your browser a domain name such as www.watchguard.com.

How to Flush Windows DNS Cache

Internet connection problems? DNS cache corrupted? Maybe you need to flush Windows DNS Cache. If your computer is finding it difficult to reach a certain web site or server, the problem may be due to a corrupt local DNS cache. Sometimes bad results are cached and therefore need to be cleared from the cache in order to allow your Windows computer to communicate with the host correctly.

Typically, there are 3 types of caches in Windows which you can flush easily:

1. Memory Cache
2. DNS Cache
3. Thumbnails Cache

Clearing the Memory Cache can free up some system memory while clearing the Thumbnail Cache can free up space in your hard disk. Clearing the DNS Cache can fix your internet connection problem. Here’s how you can flush the DNS cache in Windows 8 or Windows 7.
