I will assume that you want to allow normal psql client access and not through a web server. There is two places you will need to configure. One is your router - you will need to setup port forwarding . The default port for connecting to the PostgreSQL server is 5432 so the router will need to forward any incoming requests on tcp port 5432 to tcp port 5432 at server address yyy.yyy.yyy.yyy (your PostgreSQL server address) If you have configured a different port then adjust accordingly. This is a common configuration option and shouldn't be hard to find. Second you will need to configure PostgreSQL to accept connections from outside your network. This is done in pg_hba.conf which is in your data folder by default. If you currently connect to the server from another machine on your network you will have a line similar to hostall all yyy.yyy.yyy.yyy/24 md5 To allow PostgreSQL to accept outside connections you will add another line such as hostall all zzz.zzz.zzz.zzz/32 md5 Where zzz.zzz.zzz.zzz is the ip address of the remote computer that wants to connect. The pg_hba.conf file has notes explaining these entries or you can read up the docs at http://www.postgresql.org/docs/8.1/static/client-authentication.html Basically this entry says you are willing to accept network connections from another computer and how they are allowed to connect and which databases they can connect to. If you allow connections from anywhere then anyone has the chance of getting into your database. It is preferable to only allow connections from a specific ip address but if they don't have a static ip address you won't be able to do that. If they have a dynamic ip address one suggestion is try and limit them to connections from the isp they are connecting from instead of just any computer in the world. -- Shane Ambler [EMAIL PROTECTED] Get Sheeky @ http://Sheeky.Biz ---(end of broadcast)--- TIP 2: Don't 'kill -9' the postmaster
Re: [GENERAL] Access to databas from the Internet
You have to either configure your router to redirect the public port to the private port. (By default 5432). Or put your database server in the DMZ (not recommended).

Re: [GENERAL] Access to databas from the Internet
Hello Lukasz! You need some port forwarding onto your router/firewall. You have to forward incoming connections on port 5432 (or the port postmaster is listening on) from IP xxx.xxx.xxx.xxx to IP yyy.yyy.yyy.yyy with the according port. If your router is a Linux machine, take a look into the iptables rules and also the HowTos at http://www.netfilter.org/ how to create a port forwarding. Be aware that this will also attackers from the internet will enable them to use exploits onto your server! So make sure, that this machine is properly secured.
