(this might be built into whatever 'modem' your ISP provided). is the Postgres port forwarded from the outside world to your server? in general if your home server is on a private local network address like 192.168.x.y or 10.x.y.z, then it can't be directly reached from the internet unless the internet gateway is configured to forward the service port in question from real.ip.addr:port to local.ip.addr:port (Postgres uses port 5432/tcp by default) -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general

When you say ISP do you mean the cloud provider or the service provider(s) from the various sites? I am assuming that that your home, office and the public Wi-Fi locations are not all using the same ISP. Is this a common SNAFU to encounter? My guess is that the firewall rules on your cloud server is only allowing connections from your home site. I spent an hour on the phone with tech support for the office's ISP; the guy insisted it could not be a problem on their side! Is there something I could be overlooking?

Re: [GENERAL] Windows ODBC connection trouble? ISP issue?
My home ISP, our cloud server, and the office ISP are all separate entities. I infer that the problem is with the office ISP - DSL provided by a phone company.

The common point in all the connections is the cloud server. You can connect from home but not any where else. Would seem to indicate that your cloud server(the server itself,not the Postgres server) is only taking connections from your home.

Re: [GENERAL] Windows ODBC connection trouble? ISP issue?
I cannot think of any special reason why the cloud server would allow a connection from my home versus any other location. I will test another location or two.

I do, it is called a firewall:) I would highly suggest checking what your firewall rules on your cloud server are. I use AWS and the rules are accessed from the Management Console as Security Groups as a for instance. I will test another location or two.
