Troubleshooting Firewall Problems in Four Steps
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.

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) Basics
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:

Windows Firewall
Windows 7 native firewall is based on two sets of rules that complement each other. The basic Windows Firewall uses simple rules that directly relate to a program or service while the Windows Firewall with Advanced Security (WFAS) allows for more complicated rules that filter traffic on the basis of port, protocol, address and authentication.
