The Tor software does not support UDP. The feature request UDP over Tor![]()
was created in 2013 and closed as won't fix
![]()
by upstream, The Tor Project in 2018. It is therefore highly unlikely that the UDP over Tor feature will ever be implemented. This is unspecific to Whonix.
Tor provides a DnsPort but that is unrelated.
If UDP is urgently required in Whonix, a limited workaround is provided. For the most secure method, see Tunnel UDP over Tor.
