The openVPN manual states in the section "--proto":
"There are certain cases, however, where using TCP may be
advantageous from a security and robustness perspective,
such as tunneling non-IP or application-level UDP proto‐
cols, or tunneling protocols which don't possess a
built-in reliability layer."
Is someone can provide links to discussions with more information about what would be included as "non-IP or application-level UDP protocols" and of examples of protocols without built-in reliability layer", I would appreciate it. From a technical perspective it is not clear to me what these would include specifically in this context.
