Tunneling and Security

Over the years, different forms of tunneling have been implemented. Tunneling IP traffic over the X.25 packet layer protocol was common practice in the early days of the Internet. Today, tunneling is increasingly a security issue. Tentun is a tunneling project that introduces the innovative concept of modifying packet traffic to include completely transparent covert traffic to existing streams of data. Tentun also aims at unifying different tunneling implementations.
