Application proxy firewalls

A proxy or proxy server is a technique that acts as an intermediary between a Web client and a Web server. A proxy firewall acts as a gateway for requests arriving from clients.

When client requests are received at the firewall, the final server destination address is determined by the proxy software. The application proxy translates the address, performs additional access control checking and logging as necessary, and connects to the server on behalf of the client.

The DB2 Connect™ product on a firewall machine can act as a proxy to the destination server. Also, a DB2® database server on the firewall, acting as a hop server to the final destination server, acts like an application proxy.
