I'm having trouble getting a connection to Postgres to work from
outside of my local network. It was working fine at one point. Then I
had to change IP addresses and I can't get it to work. This is what
I've done.
On the computer with Postgres installed I have this in the pg_hba.conf
file:
host all all 207.6.93.152/32 md5
This will only allow the host at 207.6.93.152 to connect. If you're
trying to reach the database from any other system, that won't work.
I know the user name and password etc are correct because I can
connect locally using the same stuff. The only things that have
changed since it was working is IP addresses. I confirmed they are
right. Also when trying to get it working I noticed that the port
forwarding got disabled somehow so I set that up again but still no luck.
Generally the troubleshooting works like this:
1) Confirm psql connects from the host (with the default, sockets based
connection)
2) Confirm psql connects using TCP/IP on that same host. So "psql -h
<server ip>" on the server itself. If that doesn't work, probably an
issue with listen_addresses or pg_hba.conf
3) Connect to the database from another host on the same local network.
If this fails, check pg_hba.conf again, and make sure the server's
firewall is configured to allow connections to the port
4) Connect from an outside network. Now any problem you have should be
limited to just being related to things like port forwarding.
