No. As Aaron said, the connection would be initiated from a source port < 1024 (by default). If you have a stateful/connecection-tracking firewall, then just opening port 988 from clients to servers should be enough. If your firewall is not stateless/connection-tracking, then you would need a rule for all servers with source port 988 and destination ports < 1024 to all clients. b.
