Viscosity connects, no ping to destination
Posted: Tue Nov 30, 2021 7:12 am
Hello,
try to connect from a DS lite line (only IP v6) to a Synology OpenVPN server on a classic IP v4 and v6 internet connection. The problem is that the connection is possible but there is no connection (and no ping) to the Synology (192.168.178.5). I think there might be a problem with the routes, but I cannot interpret it.
Connecting from another internet connection is possible, also different Mac (macOS 11 and macOS 12).
Thank you very much for your help!
