You also did not state which O/S you are working with or which version of PostgreSQL you are using.
In either case, you still need to update the pg_hba.conf file and then reload.

The default port for PostgreSQL is 5432.
To allow external ip access, you need to specifcally add the ip's  to the pg_hba.conf on the PostgreSQL server
and then reload the PostgreSQL cluster. IE: pg_ctl reload

Hi there,
I am trying to install a postgres cluster in a XenSever VM: I did not have
any difficulties in compiling, installing and starting the DB. The problem
is that I can not access to this db from an external machine: I tried to
configure port forwarding through iptables as well as I did for ssh
connections (ssh is working correctly).

Actually I do not have psql in XenServer host, I am using a third server and
this is iptables rules I am trying:

iptables -t nat -A PREROUTING -p tcp --dport 5997 -j DNAT --to-destination
10.0.0.4:5997


I also triet do scan port by nmap and I received this output:

nmap -p 5997 pippo.eu

Starting Nmap 5.00 ( http://nmap.org ) at 2015-06-12 16:38 CEST
Interesting ports on pippo.eu (xxx.xxx.xxx.xxx):
PORT     STATE    SERVICE
5997/tcp filtered ncd-pref




This is psql output:

psql -p 5997 -h pippo.eu
psql: could not connect to server: No route to host
        Is the server running on host "pippo.eu" (xxx.xxx.xxx.xxx) and
accepting
        TCP/IP connections on port 5997?


Port 5997 is open in virtual machine and accept connections.


Can anyone help me? I'm going crazy.... :(

Thanks in advance.

Meph
