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)". -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1500826 Title: Missing --no-dtls option To manage notifications about this bug go to: https://bugs.launchpad.net/network-manager-openconnect/+bug/1500826/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
