EverServe running on a network through firewalls

Everserve package delivery is based upon RMI. How you get the RMI protocol to work through a firewall is dependent on whether you are configuring permission for inbound or outbound traffic.

See http://java.sun.com/j2se/1.3/docs/guide/rmi/faq.html#firewall for information on configuration of RMI through a firewall or using an HTTP-tunnel.
