How is Port Forwarding Configured?

How is Port Forwarding Configured?

Software ports are numbered connections that a computer uses to sort types of network traffic. A port may support incoming traffic, outgoing traffic, or both. A few services, such as FTP (on port 21), and HTTP (on port 80), are assigned by default to open ports where operating systems can easily find them easily. When a port is opened a service is assigned to it, for example, an online game. For security, by default all ports to the Internet, and most LAN ports are closed so that traffic cannot flow through them.

Common ports are listed in Port Numbers for Port Forwarding.

To test whether your port forwarding is secure, see How Are a Computer's or a Router's Ports Secured?

D-Link WIRELESS ROUTER CONFIGURATION

WIRELESS ROUTER CONFIGURATION

These instructions are meant for residents of Palo Verde, Verano Place, Gabrielino, and Santiago apartments.

Use the following checklist to ensure that your computer is configured correctly for use in Palo Verde, Verano Place, Gabrielino, and Santiago apartments.

1. You should connect an ethernet cable from wall jack directly into the WAN port on your router/access point.
2. We recommend that you have some kind of encryption enabled- at least WEP, and preferably WPA or WPA2 which are far more secure than WEP.
3. We also recommend (for increased security) that you enable MAC filtering. This feature allows you to identify which wireless cards the router will "speak" to, and it can specify that your router ignore all other ethernet cards. This ensures that only computers you approve of can use your access point. You can find your MAC address by clicking Start -> Run, typing "cmd", clicking "Ok", and then typing "ipconfig /all" in the console window that pops up. Your MAC address is listed next to Physical Address. If you have more than one network adapter, such as an ethernet and wireless, you probably have more than one MAC address. Make sure to use the one from the wireless adapter.

The following is a guide to give you a general idea of how to configure your router/access point. The guide uses a Linksys WRT54G as a basis.

Step 1 – Resetting

Connect the power cord Unplug ALL Ethernet connections Hold down the reset button for at least 15 seconds

Step 2 – Cable Setup

Connect your computer (PC or MAC) to any one of the LAN ports, only Connect the Internet (WAN) Port to ResNet DO NOT connect the wall port to any port on the Router yet!

You must secure your wireless network, failure to do so may result in disconnection by ResNet. We recommend that you use WPA instead of WEP.

For WPA (recommended)

• Click “Wireless”
• Click “Wireless Security”
• Select “WPA Pre-Shared Key” in the “Security Mode” field
• Set the "WPA algorithm" to "TKIP"
• Type in your WPA Shared Key. It should be between 8 and 32 characters- the longer the better. Make sure it is something you can remember but that is hard to guess. You may want to write it down, temporarily, so that you can remember it for when you configure your computer to connect to the now-secure access point.
• Click “Save Settings”

For WEP:

• Click “Wireless”
• Click “Wireless Security”
• Select “WEP” in the “Security Mode” field
• Bubble “1” under the “Default Transmit Key” field
• Select “128 bits 26 hex digits”
• Enter a desired passphrase into the “Passphrase” field
• Click “Generate”
• Carefully write down the code generated in the “Key 1” field on paper, and store it in a safe place. THIS IS YOUR WEP KEY, it will be needed later on.

How to retrieve your Windows Vista password

One of our most popular articles is a guide on how to reset your Windows Vista password using the password reset disk. However, if you did not create a password reset disk and you have forgotten your password, you cannot login and use your computer. In these situations there are certain tools that can help you out, most of them being commercial solutions, such as Active Password Changer. Still, there exist also some free alternatives, one of them being Ophcrack. In this guide I will show how to get Ophcrack and how to use it to crack and retrieve your Windows Vista password when you don't have any password reset disk at hand.

First, go to the Ophcrack site and download the Live CD. Please make sure you download the Windows Vista Live CD and not the one for Windows XP. The Live CD is a disc image saved as an '.iso' file which you need to burn onto a CD. Use a good CD/DVD burning solution to write the image file on a blank CD. If you don't have any, you can try CDBurnerXP. It is free and it works very well.

Once the disc is ready, you need to boot directly from the CD you just created. If you don't know how to do this, please read this guide.

Once you manage to boot from the Ophcrack Live CD, you will have three choices on how to launch the tool. The first two options will launch Ophcrack in a graphic mode. If you have problems with the first mode, then reboot and choose the second. Depending on the hardware configuration, on some computers both modes will work. On the computers i have tested it, sometimes the first mode did not function properly but the second one always worked just fine.

If you don't want any graphics, then choose the third option which will launch Ophcrack in text mode.

Once you have chosen a mode, Ophcrack will start loading and retrieving your passwords. This can take a few minutes, depending on your configuration and how strong the current passwords are. Please be patient and wait until the screens with text like the one below disappear and the graphical user interface is displayed.

Once the tool loads, it will show a screen like the one below. Please be patient as not all graphical elements will be shown at once. This is because Ophcrack will be busy cracking the passwords for all users registered on the PC.

When finished, Ophcrack will show you all the registered users from your Windows Vista and their corresponding passwords in the NT Pwd column.

Write down the password for the user that interests you, reboot your PC and login to Windows Vista using the password you just recovered.

Use System File Checker To Repair Windows Vista System Files

When you heavily tweak different aspects of Windows Vista, liken when transforming it's looks to be like a Mac OS X chances are that, if you are not careful, some of your system files will become corrupted or get deleted and lost in the process. This can sometimes lead to Windows Vista not working properly. In such scenarios, you either use System Restore or System File Checker to restore your system files.
When using System Restore you will restore not only your system files but also your settings to a previous state. If you want to restore only your corrupted or deleted system files, it is better to use System File Checker. In this article I will show you where to find this tool and how to use it.

In order to use System File Checker, type in the Start Menu search field the word 'command'. The first result should be the Command Prompt. Right click on it and select 'Run as administrator'. After the UAC (User Account Control) prompt will show up, click on Continue.

Alternatively, you can find the Command Prompt by going to 'Start -> All Programs -> Accessories'.

In the Command Prompt window, type sfc and you will see a command list with explanations for each one of them.

The most common and useful commands for System File Checker are the following:

• sfc /verifyonly - Scans integrity of all protected system files without repairing any.
• sfc /scannow - Scans integrity of all protected system files and repairs files with problems when possible.

Depending on your system, the scan can take up to 15-20 minutes. If the scan encountered system file errors and it fixed them, you will see a confirmation message just like in the screenshot below.

Create System Restore Point

System Restore is a feature that allows users to restore their system to a previous state. It offers a way to undo all the changes in the system files, registry keys, installed programs, etc, to a previous state, without affecting personal files such as documents, photos or e-mails. It was first implemented in Windows Me and since then it was included in both Windows XP and Windows Vista.

By default, Windows Vista creates the so called "restore points" every day. The restore points are created automatically, before any significant system event such as the installation of a program, device or system update. Also, restore points can be created manually by the user.

When something goes terribly wrong with your system you can restore it to a previous state and you will be able to use it again. In this tutorial we will show you how to do that using System Restore.

There are several ways to find System Restore. The easiest is to type "system restore" in the Start Menu search field and press Enter or click on the search result.

The main System Restore window will open. You have two options: to restore your system to a previous restore point or to create a new restore point.

First, we will show you how to create a restore point.

In the lower part of the System Restore window you should see a link saying open System Protection. Click on in.

A new window called System Properties will pop-up. Here you can select the drives which will be included in the restore point. To select them, simply click in the appropriate check-boxes and then click the Apply button.

Now you can create a custom restore point for the selected drives. To do that, click the Create button, type the name for the restore point, and click the Create button once again.

Windows Vista will create the restore point for the drives you selected. After a while you will receive the confirmation that the restore point was created.

To restore your system to a previous state you can use the recommended restore point or you can choose a different one. The Recommended restore option will restore your system to the most recent restore point.

If you select the second option, after you press the Next button, you will see a list of available restore points. Select the one you prefer and press the Next button once again.

Now you are asked to confirm your restore point. Click the Finish button and System Restore will restart your computer to apply the necessary changes.

When the process is finished your system will be back to the state you selected.

How to restore your files

A few months ago I wrote a tutorial showing you how to backup your files in Windows Vista. In this article I will show you how to restore those backups using the Backup and Restore Center.

In the search field of the Start Menu type the word 'restore' and then click on the Backup and Restore Center shortcut. Alternatively, you can go to Control Panel -> System and Maintenance -> Backup and Restore Center.

In the Restore files section, you have two options: Restore files and Restore computer. In this tutorial, I will cover the Restore files procedure.

How to restore files

After clicking on the Restore files button, the wizard will ask if you want to restore files from the latest backup or from an older one.

Choose the option you prefer and then click Next.

Now you have to browse and add the files and folders that you want to restore.

First, click on the Add files or Add folders button. Then, find the files or folders that you want to restore, select them and click on the Add button. Repeat this procedure until all the files or folders that you want to restore are present in the Restore Files window.

Notice: You are allowed to browse only through files and folders that were previously backed-up.

If you can't find a specific file or folder click on the Search button. Then, type the name of the folder/file in the search field and click on the Search button. If the folder/file has been found, select it and click on the Add button.

Tip: If you don't know the name of the file you are looking for, but you do know what the file type, you can search for all the files that have the same extension (.doc, .mp3, .xls, etc.) as the file you are looking for. For example, type '.doc' in the search box and click on the Search button.

After you have finished adding the files or folders that you want to restore, click on the Next button.

Now, you will be asked if you want to restore the files in their original location or in a different one. Choose the option you prefer and then click on the Start restore button.

Notice: If the same file that you want to restore is found in the same location, you will be notified and you will have to choose one of the following options: 'Copy and Replace', 'Don't copy', 'Copy, but keep both files'.

After a while, the restore process will be completed. Once you are notified that the files were restored, click on Finish.

NOTE: Windows Complete PC Backup and Restore is not included in Windows Vista Home Basic or Windows Vista Home Premium.
