What is the purpose of the VoIP Ports Firewall Test and how can it help me?
The ISPgeeks VoIP Ports Firewall Test attempts to test a specific set of the most
commonly used VoIP ports (outbound only) on your PC and network. The ports selected for this test are
considered to be the most widely used by residential and small business VoIP products.
This test will check available ports for both software and hardware based VoIP products.
If the VoIP product you are testing for fails it's specific test then you will need to
configure your firewall to open those ports.
If you have a VoIP product not shown in our test and want to have it included please email us at firstname.lastname@example.org.
What is a Hardware Firewall?
A hardware firewall is usually a small box that sits between a modem and a computer or network. The firewall is either based on "network address translation" (NAT)
which hides your computer from the Internet or NAT plus "stateful packet inspection" (SPI) for more protection. There are three basic types of hardware devices that include
firewalls for home users, Wired Routers, Wireless Routers, and Broadband Gateways. They are inexpensive enough to be used with one computer and can also be used to create a home
computer network. They can be used in addition to a software firewall on each computer because they run on a separate box preventing most compatibility problems.
Should I use multiple firewalls or combinations of hardware and software firewalls?
The answer is generally no, you do not need to use a combination of hardware and software firewalls and NEVER use two personal firewall software products at the same time.
Fully uninstall one before installing another to prevent compatibility problems. Also, turn off the firewall built into Windows 7, Vista and XP Service Pack 2/3. After installation,
be sure to test it with an online service like ISPGeeks and Shields Up to make sure that it is configured correctly.
