4.2.1.5 IP Security
IP security allows the system administrator to restrict incoming and outgoing TCP/IP
sessions and access to the serial port. Connections are allowed or denied based upon the
source IP address (for incoming connections) or the destination IP address (for outgoing
connections).
IP security information can be added to the IP local host table. To add an entry, specify an
IP address and whether to allow (Enabled) or deny (Disabled) connections. An address with
0 or 255 in any segment restricts all addresses in that range. For example, the command
below disables outgoing connections for all addresses between 192.0.1.1 and 192.0.1.254.
Single addresses can also be specified. See Change IPSecurity in the Device Server
Reference Manual for more information.
Figure 4-6: IP Security Command
To view the host table entries, enter the Show IPsecurity command. To remove an entry,
use the Delete IPSecurity command followed by the IP address that you want to remove.
4.2.1.6 WINS
If WINS is enabled, the MSS will broadcast a WINS name announcement at boot time, and
answer broadcast WINS name queries. Other hosts can locate the MSS this way. The MSS
will rebroadcast whenever its IP address or name changes.
To enable WINS, enter the following command.

4.2.2 IPX (NetWare) Configuration
Four NetWare settings can be configured: routing and encapsulation parameters, the
internal network number to use for internal routing, and the NetWare loadhost to use at boot
time.
4.2.2.1 Routing and Encapsulation
The first layer of an IPX Ethernet packet is the frame type. It includes routing information.
By default, the MSS is configured to handle packets of all four NetWare frame types.
If more than one frame type is in use on the LAN, the MSS will advertise itself as a router
to the network using its internal network number. This behavior allows nodes and
fileservers to access the MSS regardless of the frame type being used.
