USER’S GUIDE270 CyberSWITCHSome of these packets are overloaded in that they are not just keep-alive packets but arecontrol packets needed for the application to run successfully and hence have to be routed likeregular SPX data packets. If any NetWare application does not seem to work across WANs, it maybe because of the mishandling of these packets and can be traced by disabling SPX keep-alive spoofing.This above described implementation is followed for keep-alive packets received over the LAN andthe WAN. If a keep-alive is received over the WAN and it is determined that a spoofed keep-aliveshould be generated, it will be returned over the same WAN connection on which it was received.The parameters for SPX spoofing are configured for each device. The SPX spoofing option can beenabled or disabled. By default the option is enabled. When disabled the SPX keep alives are routedwithout any special handling. If the option is enabled the SPX spoofing duration time T is specifiedin minutes. The default is set to 120 minutes.IPX T YPE 20 P ACKET H ANDLINGCONFIGURING IPX TYPE 20 PACKET HANDLINGU SING CFGEDIT1. Press 8 from the IPX menu to configure IPX type 20 packet handling.
