in the cvs main branch you find a new example how to setup a xmlBlaster master/slave cluster where the slave is behind a firewall which only allows one outbound socket connection:
Example of a slave xmlBlaster cluster node 'frodo' running behind a firewall which allows outbound socket connection only.
On the outside we have a master xmlBlaster cluster node 'heron':
clientA -+ +- clientX | | ... +-> frodo ---SOCKET---|firewall|--> heron -+- ... | | clientN -+ +- clientY
For more info or to play with it see
