Hi,
I have used Daffodil replicator in a similar situation earlier.
It is necessary that master and slave database should be exposed to
each
other.
The problem might have occurred due to deployment of firewall in the
network
that is preventing the connection to establish.
The solution could be found out by using routers or any other mean so
that
master and slave servers are exposed.
