By deploying a WAF in front of a web application, a shield is placed between the web application and the Internet.

le client se connecte au proxy et le proxy refait une connexion avec le serveur cible. un firewall comme un routeur ne changent pas la connexion tcp (ils ne sont pas vus dedans) ils inspectent seulement les paquets ip qui passent pour les autoriser, les bloquer ou les rediriger vers la bonne adresse, en ne modifiant que l'entête ip. et By deploying a WAF in front of a web application, a shield is placed between the web application and the Internet.

Interesting question. I've never associated the two before, but if you look at the definition of 'proxy', meaning something that performs an action on your behalf, then that would mean a firewall, in many cases, is a proxy.
