Upgrade Firmware New firmware versions are posted at www.NetworkEverywhere.com and can be downloaded for free. If the Router can access the Internet already, there’s no need to download a newer firmware version, unless that version has a new feature that you want to use. (To learn about any new firmware with new features, visit www.NetworkEverywhere.com.) Loading new firmware onto the Router does not always enhance the speed or the quality of your connection.

To upgrade the Router’s firmware:

1.Download the firmware upgrade file from www.NetworkEverywhere.com, and extract the file using archive software such as WinZip.

2.Select the Help tab (see Figure 6-10).

Note: By upgrading the Router’s firmware, you may lose the Router’s configuration settings.

3.Click Upgrade Firmware to display a new window.

4.Click the Browse button to find the firmware upgrade file you extracted.

5.Double-click the firmware file you extracted. Click the Upgrade button and follow the on-screen instructions.

IP Filtering

From the IP filters screen, shown in Figure 6-11, you can block specific inter- nal users from accessing the Internet and enable Virtual Private Network (VPN) sessions. You can set up filters by using IP addresses or network port numbers (or a range of ports).

Filtered Private IP Range To set up a filter using IP addresses, enter the range of IP addresses you wish to filter in the IP address fields. Users with filtered IP addresses will not be able to access the Internet at all. If you only want to filter one IP address instead of a range of IP addresses, enter the same value into both fields. For instance, if you wish to filter the PC with the IP address of 192.168.1.5, enter 5 into both fields on one line: 192.168.1.5 ~ 192.168.1.5. Click the Apply button when finished.

Filtered Private Port Range To filter users by network port number, enter a network port number or a range of network ports. Select the protocol for each port number you want to filter, TCP or UDP. Enter the port numbers you want to filter in the port numbers fields. Users connected to the Router will no longer be able to access any port number listed there. Click the Apply button when you’re done.

Time Filter This feature allows you to block access to the Internet during pre- set times.
