I hooked up Ethereal. I saw tcp packets from my other machine but it
looked like the destination was port 3741 even though I had configured
5200? I changed to use 3741 and still not working. I see the messages
coming but I also see a lot of errors sent back saying incorrect
checksum.
Any other info I can provide to you?

Hi Shreedhar
I'm trying to test the cross-subnet support.
It seems really easy when reading the document below.
Two properties set and away you go.
However I have done this and trying to get two machines clustered from
different subnets it don't seem to work?
Basically I just added this to my test application?
_properties.put(ServiceProviderConfigurationKeys.IS_BOOTSTRAPPING_NODE,
"true");
_properties.put(
ServiceProviderConfigurationKeys.VIRTUAL_MULTICAST_URI_LIST,
"tcp://10.6.2.89:5200");
//initialize Group Management Service
m_GMS = initializeGMS(_properties);
10.6.2.89 is my local machine here. Does it matter if bootstrapping is
true on the other machine but its IP is not in the list?
The bootstrapping needs to be set to false on the other machine if its
address is not on the list. Could you try that ? The cross subnet
support work is yet to thoroughly tested. Its not battle tested yet.
Doesn't matter commented that line out and ran that code on the other
machine which is on another domain within our company and it doesn't
seem to work. The machine can ping my machine so it can see it.
What do I do now? How do I debug this or how do I tell if it is being
setup correctly for cross-subnet?
You could take a tcp dump and load the file in Ethereal/wireshark to see
if communications are happening between the two machines on port 5200.
Or am I doing something wrong?
The bootstrap node value should be either true or false. Could you try
that and let me know?
TIA

Hi I have a few questions
Was wondering if there is any documentation on bootstrapping the JXTA in
order to facilitate cross sub-net/firewall communications?
Here's a document I wrote up. Please let me know if this is helpful and
works as described.
