Configuration Interdependencies 209
NetWare MultiProtocol Router for ISDN 3.1 provides a number of
filter and spoofing mechanisms on the network protocol and ISDN-
Controller level.
Filters and spoofings operating on the network protocol level are
configured via INETCFG.NLM and FILTCFG.NLM. For detailed
information on usage and configuration of these filters, refer to the
NetWare MultiProtocol Router 3.1 Configuration guide.
Filters and spoofings operating on the ISDN driver level are exclu-
sively configured via "WAN Call Directory" in the INETCFG.NLM.
Configuration and usage are described in detail in Chapter 7, "Con-
figuring ISDN Call Destinations".
The main difference between mechanisms on the ISDN driver and the
network protocol level is that the latter is always active even if there
is no active logical connection between two sites. Filters and spoofing
mechanisms on the ISDN driver level are terminated when the logical
connection is cleared.
A number of filter and spoofing mechanisms can be configured on the
network protocol and the ISDN driver level. Thus, if you want to
disable a special mechanism, make sure that it is disabled on both
levels.
