I am learning JXTA and want to master it. I downloaded the tutorial programs from jxta website I have run all those programs from only one PC and worked perfectly fine. But I want it to work over internet. My friend also has an internet connection. We tried to run socket client on his machine while socket server program was running on my machine. I also tried to make myjxta (a jxta p2p application) to work over internet but had no success. We both have ADSL connection and has D-Link ADSL router GLB-802C. While setting up the router I did entered username and password. There not any proxy configuration for browser. So is it required to do the proxy configuration for JXTA if yes how should I do it..
The ipconfig for ethernet is as follows

I am trying to do it since week, I need help to understand this.... I want some guidelines how should I proceed with this because there is not much information available for JXTA on internet. Thank you for any help ..
I am changing a question a little bit I want to run MyJXTA (a readymade JXTA application downloaded from JXTA website) to work over internet. I did provided configuration screenshot links in the comment, as well as screenshot of MyJXTA application when I run it. thanks for any help...

I just figured out that there is some problem with tcp server socket and my isp. I did confirmed it with python SOCK_STREAM here is the thread - Python SOCK_STREAM over internet . Only Datagram works on my pc . I do not know whether jxta used tcp server socket or not. Can there be any other problem ?

From a networking perspective, you've got two machines, each of which is behind a firewall.
Unless their is some 'broker' service that is publicly accessible to both of you, you're not going to be able to connect to each other without poking some holes in your firewalls. I'll bet the simple example code you downloaded doesn't provide for that 'broker'.
From the docs I found on the java site, it sounds like the thing your missing is a 'Public Rendezvous peer'.
The java site has lots of stuff on jxta, a forum and an IRC channel.
If you want to debug this at the network level, wireshark can help.
you need to bring up a rendezvous server outside of both your NATS.
Those links describes some of the options you can use:

- http://onjava.com/pub/a/onjava/excerpt/jxtaian_2/index2.html?page=3
if I remember correctly from my JXTA days, you can also use a public rendezvous server.
Hi (from the leader of the two latest release of JXTA for Java), you need to set-up a RDV peer with a public IP address. Then, this peer must be set as a seed in your two EDGE peers. Then, socket communication should work (it does in our tests). Cheers.
