JXTA private net problems

I managed to run my private net in a subnet already but I still try to 
get my private net up and running in the Internet. I even put my server 
to another ISP. It is now located in a DMZ at my company. Before it was 
located behind a router with portforwarding which I guess is the problem 
in both cases!

When I browse to http://83.64.248.67:9901/ where my Rdv is running on I 
get the following message:
JXTAHELLO tcp://10.1.14.132:60762 tcp://192.168.13.6:9901 
urn:jxta:uuid-59616261646162614E504720503250330DC9C4666CFF461CAA6DF1F86AFAC32003 
0 1.1

tcp://10.1.14.132:60762 is the IP I am connecting from and 
tcp://192.168.13.6:9901 is the local IP of the jxta server. Now could  
the problem be that the server IP should actually be 
tcp://83.64.248.67:9901/ and that this might confuses JXTA? What could I 
do to solve this? Directly connecting the server to the Internet seems 
to be the only solution!?
