IPX Type 20 Packet Handling

USER’S GUIDE

Some of these <SYS> packets are overloaded in that they are not just keep-alive packets but are control packets needed for the application to run successfully and hence have to be routed like regular SPX data packets. If any NetWare application does not seem to work across WANs, it may be because of the mishandling of these <SYS> 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 and the WAN. If a keep-alive is received over the WAN and it is determined that a spoofed keep-alive should 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 be enabled or disabled. By default the option is enabled. When disabled the SPX keep alives are routed without any special handling. If the option is enabled the SPX spoofing duration time T is specified in minutes. The default is set to 120 minutes.
