Advanced Port Scanner is a free but robust network open ports scanner developed by the famous remote controller Radmin's official site. It features professional yet user-friendly GUI, abundant features, as well as very fast scanning speed.

Today, all laptops come with wireless network adapter. At the same time, the huge convenience of wireless network is obvious. But since it is subject to technical bottleneck, the stability and quality of wireless network always can't catch up with wired network. That is to say, the most annoying thing when using a wireless network is the poor signal, especially you don't know which one is better.

Above all things, you have to know what port forwarding/port mapping is. Port forwarding refers to the mechanism of packets forwarding. Its essence is firewall's configuration strategy. But its function mainly focuses on packets forwarding, in order to achieve the purpose of operating specific packages (IP address parsing and filtering based on destination port number). As a consequence, it is generally taken out as an independent concept.

The design idea of NetLimiter is to completely and reasonably control, distribute the Internet traffic/bandwith for various network software, so as to make sure they can run smoothly at the same time without disturbing each other. While in AppNee's view, its powerful and perfect Internet connection monitoring & statistics functions (with very comprehensive data) are really helpful to system security and computer efficiency management.

There are always a lot of tech news sites falsely beautify Network Spoofer and zANTI such as these tools as "one of the Android penetration testing apps". AppNee would say they were only born for hacking Wi-Fi network from an Android phone - some guys only use it for fun; but some others for illegal business deals.
