Re: 答复 : Re: [JXTA user] JXTA private net problems

chenliguo, hello.

An Internet-based private JXTA net should work as well as it does on a
single subnet.

A couple possible explanations of why your private net may not work on
the open Internet:

1) The rendezvous is behind a packet filter the is blocking edge peers
attempting to connect.

2) The rendezvous is behind a consumer grade home router that is changing=
 port numbers
if you are using port-forwarding.

- Check your OS security log files to see if packet filter violations
are occuring on any JXTA ports.

- Does your rendezvous peer ever output a "CLIENTCONNECT"?

- Does your edge peer ever output a "RDVCONNECT"?
