Title : Virtual Private Network (VPN) traffic leakages in
dual-stack hosts/ networks
Author : Fernando Gont

Abstract:
The subtle way in which the IPv6 and IPv4 protocols co-exist in
typical networks, together with the lack of proper IPv6 support in
popular Virtual Private Network (VPN) products, may inadvertently
result in VPN traffic leaks. That is, traffic meant to be
transferred over an encrypted and integrity protected VPN connection
may leak out of such connection and be sent in the clear on the local
network towards the final destination. This document discusses some
scenarios in which such VPN leakages may occur as a result of
employing IPv6-unaware VPN software. Additionally, this document
offers possible mitigations for this issue.
