Just installed mongodb on centos 6. trying to connect to mongo sh with command "mongo" but got this error message: 2015-09-26T07:07:35.309+0000 W NETWORK Failed to connect to 127.0.0.1:27017 after 5000 milliseconds, giving up. 2015-09-26T07:07:35.316+0000 E QUERY Error: couldn't connect to server 127.0.0.1:27017 (127.0.0.1), connection attempt failed at connect (src/mongo/shell/mongo.js:179:14) at (connect):1:6 at src/mongo/shell/mongo.js:179
however, once i stop my firewall (iptables stop) i can access mongo shell here is my iptables:

Searched and tried different solutions. remove lock, repair; reset iptables, nothing helps.
These are the iptables's log of dropping packets

can't figure why its still blocking 27017.
