DynVPN

DynVPN is a powerful software tool that allows you to create Virtual Private Networks with ease, ensuring encrypted traffic between networks. Using DynVPN, you can quickly set up a secure Virtual Private Network between multiple networks that have only dynamic IP addresses. It's worth noting that this Virtual Private Network provides unparalleled security for every computer in the network, including those behind gateways. Furthermore, it assigns each computer a unique static IP address.

Our team at Itzgrund.net successfully utilizes DynVPN to connect remote networks to the main network in Lahm through the Internet. Having used the software ourselves, we can vouch for its reliability, safety, and effectiveness.

DynVPN has minimal hardware requirements, as it consists of only two Python scripts. The first script is a CGI script called "nexus," which runs on a server with a static IP or a dyndns name. The second script, "packthread," runs at the gateways of each connected network. This setup allows you to use your webserver to function as the DynVPN server.

In terms of software requirements, DynVPN needs Python as the interpreter for both scripts. Additionally, it requires IPsec in the kernel of the gateways (you can refer to FreeS/WAN for a patch) and FreeS/WAN on the gateways themselves.

To get started with DynVPN, you can easily run the "packthread.py" script when you go online (via /etc/ppp/ip-up.d) or when your IP address changes. After a few seconds, DynVPN configures and updates your routing tables, providing you with seamless access to other networks.

Overall, DynVPN is an excellent Virtual Private Network software tool that offers robust security and a range of features that cater to your networking needs.
