Ip Filters And Winsock Compatibility; Configuring The Instant Internet Unit In A Multiple-Unit Environment - Nortel BayStack Instant Internet 100-S Using Manual

To run Internet applications properly, Instant Internet requires the Winsock that
comes with this product. If it finds another Winsock, you must either delete the
preexisting Winsock file or rename it.

IP filters and Winsock compatibility

Filters apply to the Winsock server's packets, although input filters would not
apply since these packets are always generated internally and never come from an
external source. If you do not want the Winsock to be constrained by the output
filters for an interface, simply allow all traffic from Instant Internet's IP address.
For example:
ip filter winsock allow source x.x.x.x
ifconfig network outfilter winsock
The designation x.x.x.x is the IP address assigned to the network interface. This
address works because internally-generated packets destined for hosts on the
network connected to the network interface always have a source IP address of
the network interface. Refer to
information on IP filtering.
Configuring the Instant Internet unit in a multiple-unit
environment
When you use multiple Instant Internet units in an IPX network, you have several
additional options. Among these options are the ability to provide fault tolerance,
automatic user load balancing, and modified user access to individual units.
You can set specific defaults in the install.cfg file before installing the individual
workstation software, then you can use these defaults to assign specific users to
specific Instant Internet units during automatic workstation installation.
Caution: If you choose to continue installing Instant Internet while
allowing multiple versions of winsock.dll to run, you risk improper
operation of Instant Internet with Internet applications.
