Today, i've spent several hours hunting this down.
I've finally figured out, that my OpenVPN connection becomes unresponsive after visiting 2-3 websites, because my DSL router (Speedport W921V) "detects" some UDP connections as DoS attack.
This seems to be a problem of several routers and unfortunately there is no way to configure the router firewall.

Now, if i start the VPN manually with the --no-dtls option the connection works fine.
I'd really love to have this configurable in NetworkManager because i'm used to use the NetworkManager and not the openconnect CLI client.

For searchability: The router log message says "DoS(Denial of Service) Angriff fragmentation flood wurde entdeckt. (FW101)".
