Anyone hear anything about IKEv2 or higher than Diffie-Hellman group 5 with IKEv1. I’m a heavy Meraki user but our main firewall is Cisco Firepower. Just upgraded to Firepower 6.5 and they say DH Group 5 is deprecated and will be removed from a future version. Only problem is I have VPN’s with other clients using Meraki MX’s that are stuck at group 5.
Dont’t want to point fingers but it seems crazy one side of the shop is that’s deprecated and no longer considered fully secure and the other side is like uhh that’s is high as we go.
i know there is the big IPv6 thread and I’m not looking to start that with VPN I’m just wondering when is DH group 14 or 21 coming and then IKEv2.
