When an active IPv4 TCP connection between localIP:localport and remoteIP1:remoteport1 exists, it is not possible for local non-root user to create outgoing TCP connection from localIP:localport to remoteIP2:remoteport2. Why? It prevents http://www.freebsd.org/cgi/query-pr.cgi?pr=bin/65928 from resolving. Eugene Grosbein
