Hi dear Community,

My name is Bastian and I have a strange problem with my application. I setup 
JBoss on a japanese server. One server for the JBoss itself (192.168.0.60) and 
another server with a database(192.168.0.61). These two servers where behind a 
firewall which opend port 80 for incoming HTTP requests. 
The JBoss is connected to the Apache with mod_jk. 
Everything works fine. I can call the portal from outside in my office in 
Europe 
and from inside the server as well. Normally I choose the database server to 
test if everything works fine. I connect via RemoteDesktop to the japanese 
server. 
My Application has a resend password funktion, that call the java:/mail 
(mail-service.xml) funktion in JBoss to connect to an external mailserver also 
located in japan. And here I get my problem, when I resend the email from the 
inside database server or the JBoss server itself via a browser, JBoss connects 
to the email server an I receive a email. 

There he send the email when started from inside the firewall. 

java.exe:4660   TCP     pcom01:2466     g101.secure.ne.jp:imap  ESTABLISHED     
java.exe:4660   TCP     pcom01:2467     g101.secure.ne.jp:587   ESTABLISHED     


If I do that from my browser in europe or usa, I get a refused connection error 
in the JBoss console.

Here he tries to connect to himself (with 
-Djava.rmi.server.hostname=192.168.0.60) but witout this string too..:/

java.exe:4660   TCP     (src)pcom01:2542        (rmt)pcom01:http        
SYN_SENT        


I have done some research about that behaviour here in the forum and the wiki 
for quite a week now. The most issues I found were about firewall problems with 
java clients, they can't connect because the ports for RMI or so where not 
open. 
Also the wiki article about JBoss behind a firewall does not seem to match to 
my problem. 
I used TCPview to see what is going on at that moment JBoss received my 
request. 
If JBoss receive the request to send the email from inside his subnet, he open 
the connection directly to the mailserver. When I try this from my office or 
some other machine via internet TCPview shows me that JBoss tries to connect to 
himself using the external ip from the firewall. But JBoss cannot know the 
external IP by himself because he cannot connect to the external IP from 
inside. So I think JBoss takes the client remote address and replaces its own 
with it.

I tried to change the bind port of JBoss and the Java:/Mail without success.
I tried a guide in an article from this forum where to change the settings in 
the hosts file, but didn't worked too :|

I know when I make the external IP from the firewall visible for JBoss, the 
problem would disapper, but this is an unprofessional way my administration 
team told me.
Is there any way that I can tell JBoss not to replace it's IP with the one from 
the client who is doing the request? 

I am using JBoss 4.0.3 and he runs on a W2k3 Standard Edition.
Please don't punish me if have forgot a important thing to tell, but I think 
thats all I can say for now.

Thanks for any help
Bastian
