Survivability of Enterprise VPN-Clients in IPv6-only Environments
Some of you might have experienced it first hand while connected to the Troopers SSID, your VPN client might not be able to establish the tunnel with the IPv4-only gateway. Is this an isolated issue, or a general problem? If there is a problem, what is the root cause? Is NAT64 a problem for VPN clients? Let’s find out ;-)
In this talk, we will present our results from testing various enterprise VPN client solutions (Palo Alto, Fortinet, Pulse Secure, Cisco AnyConnect et. al.) in IPv6-only networks with different VPN protocols (IPSec and SSL) to answer all these questions.
