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.
