Appendix B Possible Problems : TCP/IP Subnet Connection Problem

TCP/IP Subnet Connection Problem
Router Cannot Send Back ICMP Messages
On Windows, the TCP/IP stack does not fragment data into a minimum packet size when transmitting data between subnets. It relies on the routers to do this, but the routers must be configured correctly to send an ICMP message back to Windows acknowledging that they cannot pass the data over since it is too large. In response, the stack transmits the data in smaller packets. The stack behaves in this manner by default to increase network response.
Symptoms
If you have dumb routers that are unable to send back ICMP messages, and if the stack is running in default mode, you are likely to experience problems using ftp to send data over the network. This can result in connection problems between TIBCO Object Service Broker component machines in different subnets.
Workaround
Modify the Windows registry on affected machines on both subnets. Complete the following steps:
