Title : Layer-3 Virtual Private Network (VPN) tunnel traffic leakages in dual- stack hosts/networks Author : Fernando Gont Filename : draft-ietf-opsec-vpn-leakages-06.txt Pages : 10 Date : 2014-04-24 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) tunnel products, may inadvertently result in VPN tunnel traffic leaks. That is, traffic meant to be transferred over an encrypted and integrity protected VPN tunnel may leak out of such tunnel and be sent in the clear on the local network towards the final destination. This document discusses some scenarios in which such VPN tunnel traffic leakages may occur as a result of employing IPv6-unaware VPN software. Additionally, this document offers possible mitigations for this issue.
