The connections are marked with <CIP, CPort, VIP, VPort, RIP, RPORT>.
        CIP:    Client IP address
        CPort:  Client Port number
        VIP:    Virtual IP address
        VPort:  Virtual Port number
        RIP:    RealServer IP address
        RPort:  RealServer Port number.

The hash table is used to speed up the connection lookup. The connection
entry is used keep state so that packets belongs to a connection from
the client will be sent to the server previously allocated for the
connection. It is more flexible.
