•Classless InterDomain Routing and Host-based routing via
the Netmask Table.
•IP address spoofing.
•Support for RADIUS accounting servers, ANI/DNIS, and
ICMP message logging.
•Support for a secondary and a tertiary name server.
•Randomized use of Default/Alternate Hosts for load
balancing.
•New Modem Port Features
Additional Software Enhancements
•NetBIOS over IPX support
•PAP enable/disable
•Pre-allocated system netbufs increased from 1000 to 1400
•Rezero network statistics and session statistics saved until
next call
•Unidirectional Van Jacobson compression

name or IP address when using Telnet
1-2 Overview
NetmaskTable
CIDR (Classless Interdomain Routing) or host-based routing
requires special netmasks. Special netmasks may also be useful
for debugging.
The Netmask Table allows you to configure netmasks for CIDR
or host-based routing as needed. RIP messaging/dynamic route
information must be active for host-based routing.
IP Address Spoofing
The NETServer may now be configured to spoof a single IP
address. When the NETServer identifies itself to remote routers
or other remote devices, it uses this IP address rather than the IP
address of its LAN interface.
IP address spoofing is useful when more than one NETServer
must appear to be a single router or other device to remote
networks and other routers.
Accounting Servers
The NETServer supports the following new features:
•Log accounting information to a RADIUS accounting server
such as the security feature of U.S. Robotics Total Control
Manager.
•ANI and DNIS call information
•Log ICMP error messages to a UNIX Syslog server
Accounting Server Support
The NETServer now supports event logging. You can configure
the NETServer to send event information to a Total Control
Accounting Server or a UNIX accounting server. You can also
configure the NETServer to send the event information to an
alternate accounting server if the primary server is unavailable.
Event logging is performed by transmitting a record containing
event information from the NETServer client to an accounting
server. TCM uses the RADIUS client/server model for this
feature.
