Subject: [PATCH] ikev1-policy defaults to drop
|
|
|
|
IKEv2 has been available for 16 years (RFC 4306 was published December
|
|
2005). At some point, we should be discouraging IKEv1 adoption.
|
|
|
|
To the extent that a user needs IKEv1, they can manually add
|
|
ikev1-policy=accept to /etc/ipsec.conf.
