Title : Virtual Private Network (VPN) traffic leakages in<br>
dual-stack hosts/ networks<br>
Author(s) : Fernando Gont<br>
Filename : draft-ietf-opsec-vpn-leakages-02.txt<br>
Pages : 15<br>
Date : 2013-08-22<br>

Abstract:<br>
The subtle way in which the IPv6 and IPv4 protocols co-exist in<br>
typical networks, together with the lack of proper IPv6 support in<br>
popular Virtual Private Network (VPN) products, may inadvertently<br>
result in VPN traffic leaks. That is, traffic meant to be<br>
transferred over a VPN connection may leak out of such connection and<br>
be transferred in the clear from the local network to the final<br>
destination. This document discusses some scenarios in which such<br>
VPN leakages may occur, either as a side effect of enabling IPv6 on a<br>
local network, or as a result of a deliberate attack from a local<br>
attacker. Additionally, it discusses possible mitigations for the<br>
aforementioned issue.<br>
