By default, Windows 7 firewall blocks unrequested, unapproved incoming and outgoing traffic to reduce potential threats. At times, it may also block legitimate traffic if not properly configured and may cause applications’ problems. Connectivity issues may block applications outgoing communications when your Windows 7 machine is acting as a client or block incoming communications if your Windows 7 machine is sharing data such as, sharing folders to other clients. Other connectivity issues can happen when Windows firewall allows incoming traffic from the LAN or domain but blocks traffic from other networks.
It is a good practice to keep a copy of your Windows Firewall settings together with other system-related documentation. Documentation of your system configuration may become handy during a disaster recovery exercise or when changes to your system cause undesirable results and you need to revert back to the previous settings! In order to document your Windows Firewall settings perform the following steps:
The best to way to understand WFAS (Windows Firewall with Advanced Security) is by setting up a test rule as we are going to see in this article. We will configure a firewall rule that accepts only authenticated RDP (Remote Desktop Protocol) connections from hosts on a specific or same subnet:
Windows Firewall and WFAS work together on Windows 7 computers. WFAS allows you to configure inbound and outbound firewall rules based on ports, programs, and services. In addition, it allows you to set a rule scope and authentication. In this article we will see the main configuration elements you need to know when creating firewall rules using the WFAS.
Windows Firewall with Advanced Security (WFAS) allows you to create rules based on port addresses and services, unlike the basic Windows Firewall where you can create rules based on programs. The basic Windows Firewall should be enough for the normal safe operation of your computer but advanced users can use WFAS to:
The basic Windows Firewall allows you to create rules based on programs and features only while to create firewall rules based on port addresses or services you need to use the WFAS (Windows Firewall with Advanced Security). In this article we will see how to configure exceptions based on programs using the basic Windows Firewall.
The NLA (Network Location Awareness) feature assigns your Windows 7 computer a network profile based on the properties of a network connection. When you connect to a new network, Windows prompts a dialog box asking you whether the network is a Home, a Domain or a Public network. Additionally, Windows 7 remembers the designation that you assign to the network and associates it with the properties of the network so that every time you connect to that network, the same designation will be applied.
