Unable to connect host after iptable configuration from centos 6 - centos

Question

I have to allow port 9000 so sonarqube can be accessible, so I flushed the IPTABLE and add the below configuration, but from then below things happening:
no external URL connecting
unable to FTP connect via filezilla (but
NFtp working)
Below is the configuration:
