So if you have a HTTP application level proxy does that mean you are
running a webserver ?

This is how proxies work, they respond to the client, then check the
packets being sent or received. Then the proxy connects to the server on
your behalf.

You should read up on application level filtering and firewall.

The BorderWare Firewall is almost completely based on the application
level proxies, as well as circuit level and packet level.

The firewall has proxies for http, ssh, telnet, smtp, ICQ -- by your
definition the firewall is running a web server, sshd, telnet daemon,
mail server and a ICQ server.

Michael.
