dumb newbie questiong regarding applications ....

I have a stupid question so please be patient ...

Let's say I have an application server that talks to an oracle database through tcp/ip. If the machine where the oracle database resides has a private ip address (say 10.0.0.20) and the app server resides on a machine outside the firewall (i.e. has a public ip address), how can they communicate if the firewall is doing ip masquerading (for eg., linux)? Can rules be created to so that the application talks to the firewall, and the firewall forwards those packets to the database server based on the port?

 I know people do this all the time since there are certainly web servers talking to Oracle databases inside firewalls ... Received on Mon May 03 1999 - 17:09:57 CDT
