Mod_tunnel, an Apache module, creates TCP tunnels using the Web server. It's beneficial for bypassing firewalls and exposing services available through a proxy. The module is straightforward to use and is compatible with Apache 1.3.x.
One of the things we liked most about mod_tunnel is how easy it is to set up and use. With just a few simple configuration changes, you can have your web server acting as a TCP tunnel for any kind of service that would normally require direct access. This can be a huge benefit for organizations that need to access web services, email servers, or other resources hosted behind closed networks.
Another great thing about mod_tunnel is how versatile it can be. You can use it to tunnel a wide range of protocols, including HTTP, HTTPS, and FTP, and it supports both IPv4 and IPv6 connections. Plus, because it operates at the TCP level, it's largely transparent to the applications you're connecting to, which means you can use it with just about any service that relies on TCP.
Overall, we found mod_tunnel to be a solid and reliable solution for creating TCP tunnels using Apache. It's lightweight, performs well, and is easy to integrate with your existing infrastructure. If you're looking for a way to bypass firewalls and proxies and expose otherwise hidden services, mod_tunnel is definitely worth checking out.
