The IP address of the server (xmlBlaster) is not changing,
so you think it is the client side IP address?

Is your client a java software?
On which OS?
Which xmlBlaster version do you use?

This is a fail save client:

java javaclients.HelloWorldSubscribe -session.name client/joe/session/1 
-dispatch/callback/retries -1

if the server disappears or the network disappears it will automatically 
reconnect,
