ngrok - secure introspectable tunnels to localhost
“I want to securely expose a local web server to the internet and capture all traffic for detailed inspection and replay.”

ngrok creates a tunnel from the public internet ( to a port on your local machine. You can give this URL to anyone to allow them to try out a web site you're developing without doing any deployment.

ngrok captures all traffic through the tunnel. It displays information about the HTTP traffic for your inspection. Raw request/response bytes, parsed headers and form data, JSON/XML syntax checking and more are included.

Developing services which consume webhooks can be challenging if the hooks are labor-intensive to generate. Use ngrok's replay request feature to iterate quickly on a new feature without switching contexts to generate new requests.

Criando Firewalls Dinâmicos com Iptables Recent - Tchello Mello Blog
Não seria interessante montar um firewall com regras dinâmicas que permitisse por exemplo, bloquear algum IP por ter tentado acessar o serviço de SSH mais de 3 vezes em menos de 1 minuto? Ou ainda criar alguma logística de batidas de porta (é!!! igual ao famoso tãn tãn rãn rãn tãn... tãntãn) e só assim permitir a entrada da conexão ao IP que acertou a combinação de portas! Tudo isso e muito mais é possível com o módulo recent do Netfilter.
