575 # vmnet (shared mode) network backend.

577 # Allows traffic originating from the vmnet interface to reach the
578 # Internet through a network address translator (NAT). The vmnet
579 # interface can communicate with the host and with other shared mode
580 # interfaces on the same subnet.  If no DHCP settings, subnet mask and
581 # IPv6 prefix specified, the interface can communicate with any of
582 # other interfaces in shared mode.

585 #     Must be in the private IP range (RFC 1918). Must be specified
586 #     along with @end-address and @subnet-mask.  This address is used
587 #     as the gateway address.  The subsequent address up to and
588 #     including end-address are placed in the DHCP pool.

591 #     interface.  Must be in the private IP range (RFC 1918). Must be
592 #     specified along with @start-address and @subnet-mask.
