database in the local area network?

[searain]

when we connect to interbase

we will use the ip address of the database server, such as www.mydomain.com

$databasehost = "www.mydomain.com:c:mydatabase/mydatabase1.gdb";
$databaseusername = "me";
$databasepassword = "helloworld"
if ( !$databaseconn )
$databaseconn = ibase_pconnect( $databasehost, $databaseusername, $databasepassword );

my question is could this database server doesn't connect to the internet directly but connecs to the web server in a local area network. and web server connect to the internet directly.

how will it work?

or use a router?

if the co-hosting company doesn't charge me for the physical space i use, i can put two machines there. if the web server is the only one connect to the internet, and the database connect to the web server locally, it might be just one fee charge.

besides, it will be more safe for the database server not connect to the internet directly?

thanks

I am assuming that you are considering putting the database on a seperate server for security resons. But my question to you is is this really secure. I mean if someone hacks your web box, they will easily be able to gain some access to your db server. Also using the IP address generally means using the Machines Ip addres (192.168.0.1) not relying on the DNS server to translante a URL to an IP. Thus you would connect with something like

$databasehost = "192.168.0.1:c:mydatabase/mydatabase1.gdb";

Just consider the reasons for having a seperate DB server...
