Notice that the MA makes use of the IPX router present in the IPX stack to
route packets between the CMD network and the IPX networks.
NetWare 6 servers installed with the MA enabled are capable of
communicating directly with other systems without regard for the install
option used to install them. They are also capable of routing network traffic
between IP and IPX systems.
