- # CASE:
- # Configuration file for a dual path server.
- #
- # The first network interface is connected to the internet to accept
- # requests for services running on this server.
- #
- # The second network interface is connected to a private LAN, through
- # which a number of similar servers communicate with each other.
- #
- # The server will only be allowed to accept and send specific traffic
- # matching the servers and clients defined.
