| EchoWall is a firewall configuration package for creating an ipchains-based
Linux firewall. It is optimized for the Linux Router Project (LRP), but was
originally created for a Debian platform. EchoWall's aim is simplicity for
entry-level users. It presumes the user is using a Linux box as a masquerading
firewall/router for a single Class-C address range. It manages services in an
interesting way: instead of indicating the IP addresses of machines you want to
act as servers, you instead specify them by their MAC address. When run, the
echowall script automatically detects the current IP address associated with
this MAC address. This allows you to connect a service to a machine whose IP
address is dynamically assigned. |
