I have been playing with the idea of a Java Firewall.我一直在玩的想法一個Java防火牆。 So far I have implemented a fully functional port blocker using port hijacking.到目前為止，我實施了功能齊全的港口攔截器使用端口劫持。 It scans for open ports on the network interface providing internet connection.它會掃描為開放口岸，對網絡接口，提供網際網路連線。

However port blocker doesn’ta firewall make.不過港口攔截器doesn'ta防火牆。 It is merely a baby step.這只是一個嬰兒的一步。 We need to access operating system API to be able to block ports which do not allow hijacking.我們需要進入作業系統的空氣污染指數，以便能夠座港口，其中不容許劫持。 We also need stealth mode to prevent attackers from even detecting the existence of the computer.我們還需要隱形模式，以防止攻擊者從，甚至檢測所存在的計算機。 We need to and can easily block UDP traffic.我們需要和可以輕易地阻擋UDP通信。 Then comes application access control.然後談到應用的訪問控制。
All of these can be done.所有這些是可以做到的。

I evaluated several firewalls like ZoneAlarm or Agnitum Outpost and each of them lacks in some key aspect or other.我評估了幾個防火牆一樣， ZoneAlarm或agnitum前哨和他們每個人缺乏在一些關鍵方面或其他。 In my experience their inability is most painful for power users.在我的經驗，他們無法是最痛苦的電力用戶。 So we started this intern driven project.因此，我們開始實習驅動的項目。

The question is what would be the level of interest in the user community to support a Java Firewall project.問題是，會有什麼感興趣的程度，在用戶社區的支持Java的防火牆項目。
