Although this communication doesn't go over the network, some firewall software will block this communication which inhibits BlueJ operation. Firewalls generally take one of two approaches to blocking network traffic. The second approach is to block traffic on a per-program basis.
Some firewalls only block incoming connection attempts while other firewalls may also block outbound connections. For BlueJ to work, communication must be allowed when both the source and destination IP address is Note that BlueJ must be allowed to make outbound connections or "act as a client" as well as receive incoming connections or "act as a server".
