Package: openvpn My server is running openvpn on jessie and I recently added a new client running stretch, using a similar configuration to my existing Jessie clients.
The server has both A and AAAA record in DNS (put there for other services) but jessie's openvpn defaults to listening on only v4. The stretch client first tries to connect on v6, then times out and connects successfully on v4. The timeout is long enough that I initially thought the client wasn't working at all. Possible solutions are to either specify udp4 explicitly on the client or upgrade the server to a version that supports dual stack (stretch-backports appears to have 2.4) . Maybe this should be in the release notes so people consider it when upgrading. If you agree please reassign this bug to release notes.
