Configuring Global Settings 3-29
Enabling NetBIOS Broadcast Packet Propagation
If your gateway on the Ethernet is not a PortMaster product, the netmask table is not
supported. However, you can set a static route on the gateway for each of the three
destination networks for your assigned pools (192.168.207.0, 192.168.208.0, and
192.168.209.0), pointing at one of the PortMaster routers. The identified PortMaster
then forwards packets to the proper PortMaster.
If you are using an IRX running ComOS 3.2R or later as your gateway, you can
configure the netmask table on the router also. This allows your PortMaster to listen to
RIP messages from the other PortMaster routers and route directly to each of them.
Enabling NetBIOS Broadcast Packet Propagation
NetBIOS is a programmable entry into the network that enables systems to
communicate over multiple media. NetBIOS over IPX uses type 20 broadcast packets
propagated to all networks to get and forward information about the named nodes on
the network.
NetBIOS uses a broadcast mechanism to get this information because it does not
implement a network layer protocol. Before forwarding the packets, the PortMaster
performs loop detection as described by the IPX Router Specification available from
Novell.
Full NetBIOS protocol compliance requires that the PortMaster be set to propagate and
forward type 20 broadcast packets across your IPX network router. When the NetBIOS
parameter is on, the PortMaster broadcasts type 20 packets. When the NetBIOS
parameter is off, the type 20 packets are not broadcast across the router. The default is
off.
To turn NetBIOS on or off, use the following command:
Command> set netbios on | off
Setting Authentication for Dial-In Users
You can configure the PortMaster for three authentication methods, PAP, CHAP, and
username/password login.
By default, PAP and CHAP are set to on . Dial-in users are asked to authenticate with
PAP when PPP is detected. If users refuse, they are asked to authenticate with CHAP.
