KWallBuilder is a tool for adding iptable rules based on the responses of the user.
The current version supports rules based on network layer protocol and ports. It supports TCP,UDP and ICMP protocols.
While KWallBuilder adds iptable rules, it does not guarantee that the added rules will be sufficient to completely protect the system, more details can be obtained from the application's home page.
Though the rpm provided is for SuSE, it can be used on any distribution. The rpm installs in /opt/kde3/ . The application and the icon can then be copied into the KDE directory for the distribution.
- KWallBuilder adds rules based on ports and network layer protocol.
- The added rules are restored on application startup.
- Packets of similar type (i.e. those that will result in the same rule) are queued if the first packet of the type is awaiting user response and the user response applied to them.
