Informix through a Proxy Server

Here is my situation: I am running an Informix Database server on a machine behind a firewall (No default route to the Internet). Another machine is running my web server and it can acess the database machine because it is on the same network and is trusted. I want to be able to query the database on the machine behind the firewall from a client PC over the internet. Is there any way to use a proxy server such as the web server to relay the information to the protected server, or is there a way to configure the Informix sqlhosts file on the web server to relay the SQL requests? Would proxy software such as SOCKS work? Any help would be appreciated! Rob Arciere rob@polygon.net
