Not particularly an IBO problem. The firewall is obviously
on, as events need port numbers other than 3050, which are
not being allowed to connect. Not sure of the port numbers
that are needed as I do my own event handling, so if some
else does not pop up with them here you may need to ask on
ib-support.
