With the release of v9.10.1, has anyone been able to get DTLSv1.2 working with AnyConnect sessions? (Our clients are v4.6.02074)
-If I don't specify dtlsv1.2, it will always establish the DTLS tunnel using dtlsv1.0.
-If I do specify dtlsv1.2 with the following config, the DTLS tunnel fails to establish with the message "%ASA-5-722043: Group <groupid> User <userid> IP <ipaddress> DTLS disabled: unable to negotiate cipher". Removing the "ssl cipher dtlsv1" line makes no difference.
ssl server-version tlsv1.2 dtlsv1.2
ssl cipher default custom "ECDHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES256-GCM-SHA384"
ssl cipher dtlsv1 custom "AES256-SHA"
ssl cipher tlsv1.2 custom "ECDHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES256-GCM-SHA384"
ssl cipher dtlsv1.2 custom "ECDHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES256-GCM-SHA384"
ssl ecdh-group group20
ssl dh-group group24
