Postgresql wont accept remote connections

I tried opening ports in IP Tables,,
Set Listen address to '*'
Added
host all all 23.81.27.0/24 trust
and host all all 0.0.0.0/0 trust

YouGetSignal shows the port is closed, and i can't connect to my DB via PgAdmin.

I get

could not connect to server: Connection timed out (0x0000274C/10060) Is the server running on host "23.81.27.206" and accepting TCP/IP connections on port 5432?

I already tried to reboot Postgresql, IPtables, and the server.

Any ideas?

Try adding (or uncommenting) "listen *" in postgresql.conf then restart postgresql.
