Title : Layer-3 Virtual Private Network (VPN) tunnel traffic leakages in dual- stack hosts/networks

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.
