Design and Implementation of UDP Tunneling-based on OpenSSH VPN

This paper focuses on two commonly used VPNs; OpenVPN and OpenSSH. Both VPN solutions are Open Source and are cross-platform, secure, highly configurable. OpenSSH forms part of a big research group, OpenBSD and is integrated in all routers, switches and almost all operating systems by default. Compared to OpenSSH, OpenVPN is less widely used and the research group is small. OpenVPN can be used only for tunneling purposes, whereas OpenSSH has many features and tunneling is only one of the features. The research by the OpenBSD developers is moving towards security and encryption and has not progress in the field of VPN tunneling since 2011. The only weakness with OpenSSH VPN is that is does not support UDP as the mode of communication, whereas OpenVPN can use both TCP and UDP as the mode of communication. There is a need for UDP tunnel in industries in situations where bandwidth is critical (satellite) and the default option for VPN systems is OpenVPN. The authors of this paper modified the OpenSSH implementation was by adding support for a UDP base connection to its VPN functionality so that OpenSSH can be the VPN of choice for Industries.
