Connection Monitoring: Port Magic takes the guesswork out of network troubleshooting by displaying a green icon when connected to a working home network router and by displaying a red icon when not connected or when the network is not working properly.

Security Management: Port Magic prevents intruders from connecting to your PCs by automatically closing firewall ports on your home router.

Gamer Mode: Port Magic opens ports automatically when playing a full-screen online game so you'll never miss any of the action.
