[jboss-user] [JNDI/Naming/Network] - NAT problem after migration from JBoss 4.0.5 to 4.2.3

[crazy_bytes]

Hi everyone,

as mentioned above I have a problem with NAT after migrating JBoss from
version 4.0.5.GA to 4.2.3.GA. Our JBoss specialist has retired recently and
I am the lucky guy who had to take over.

With help of his documentation and a little help from www.jboss.org and
google, I managed to migrate the existing configuration of our JBoss from
version 4.0.5 to 4.2.3.

We use multiple JBoss' in a clustered environment. Most of our clients are
connected via VPN. They did not even notice the migration. But one of our
clients is connected via NAT since he uses the same IP ranges as we do. Downloading newer applcations works fine, so our servers are available.

Before the migration he could work normally as any other client. After the
migration, everytime he tries to instanciate a bean the application crashes.

I compared the complete old configuration against the default 4.0.5
config and our current 4.2.3 config. The only difference I found was
an additional parameter in the $JAVA_OPTS var in the run.sh.

-Djava.rmi.server.hostname=<Servername>

I adopted this parameter into our current configuration, shut our
complete cluster down and restartet it. But without success. Whenever a
bean is instanciated, an exception like the following is thrown:

org.jboss.invocation.ServiceUnavailableException: Service unavailable for -1632156200 calling method public abstract com.crazy_bytes.collab.sessionBean.CollabManagement com.crazy_bytes.collab.sessionBean.CollabManagementHome.create() throws javax.ejb.CreateException,java.rmi.RemoteException

I can not reach our retired collegue and I am out of ideas. I googled over the net and searched this forum, but all I found concerning this problem is the parameter I mentioned above.

For example one JBoss is reachable as follows:
Local server IP:
    10.1.100.101
NATed server IP at the client:
    192.168.170.10
Local client IP:
    170.20.10.25

Anybody got an idea what I am doing wrong?

Best regards,
CB
