Yes, for outbound connections that the real server makes (not in response to a user accessing the virtual server), the IP address is translated to the virtual IP address identified by the static command. If the real_ip exists as a real server, then the outbound connection is counted toward the number of connections for that real server (that is, it will affect load balancing); otherwise, the connection is only translated and does not affect load balancing.
I am not sure about the static configuration for a particular port. Anyone else would like to comment?
