Chapter 9 IPX configuration and support 267Using the BayStack Instant Internet Management Software Version 7.11To run Internet applications properly, Instant Internet requires the Winsock thatcomes with this product. If it finds another Winsock, you must either delete thepreexisting Winsock file or rename it.IP filters and Winsock compatibilityFilters apply to the Winsock server’s packets, although input filters would notapply since these packets are always generated internally and never come from anexternal source. If you do not want the Winsock to be constrained by the outputfilters for an interface, simply allow all traffic from Instant Internet’s IP address.For example:ip filter winsock allow source x.x.x.xifconfig network outfilter winsockThe designation x.x.x.x is the IP address assigned to the network interface. Thisaddress works because internally-generated packets destined for hosts on thenetwork connected to the network interface always have a source IP address ofthe network interface. Refer to “Configuring an IP filter” on page 142 for moreinformation on IP filtering.Configuring the Instant Internet unit in a multiple-unitenvironmentWhen you use multiple Instant Internet units in an IPX network, you have severaladditional 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 individualworkstation software, then you can use these defaults to assign specific users tospecific Instant Internet units during automatic workstation installation.Caution: If you choose to continue installing Instant Internet whileallowing multiple versions of winsock.dll to run, you risk improperoperation of Instant Internet with Internet applications.
