Actually, I set the firewalled status per connection. Reason being if the Gnutella client is used within a larger network. For example, a school campus. It may be that incoming connections from the Internet are firewalled, but local connections (from dorm to dorm) are not. It's just a small thing though, but it would prevent any unnecesary "push" requests, as we all have noticed can sometimes not work as advertised among different versions (different developers).
