Mullvad VPN cannot connect (IPv6) (original) (raw)

Mullvad VPN cannot connect as described in mullvad/mullvadvpn-app#7412

If I disable Opensnitch with the Pause button Mullvad works instantly. No deny events are logged in Opensnitch, but when I enable "Debug invalid connections" I instantly get these "Unknown process" dialogs, correlated with Mullvad trying to connect.

Outgoing connection. Unknown process is connecting to 2a03:1b20:b:f011::a05f on UDP6 port 32340. Executed from source IP 2003:c6:5737:bc00:f755:6e57:3ff1:4385, destination IP 2a03:1b20:b:f011::a05f, Dst Port 32340, User ID 1000 (matt), Process ID 0

Reproduction

  1. Activate Opensnitch with GUI with "Debug invalid connections" enabled
  2. Try to connect with Mullvad. The "Unknown process" dialogs will appear.
  3. Disable Opensnitch. Mullvad connects successfully.
