I terminate http and https on the ACE. Within the L4 multi-match policy exists a class for inspection purpose.
The class itself filters on
port misuse p2p
port misuse im
port misuse tunnel
The action for a valid match is reset.
Somehow WebDAV traffic gets matched by any of the above criteria.
The only chance i have to enable WebDAV is to disable/remove the inspection from the multi-match policy.
Is this a "works as designed", "possible bug" or "bad configuration" issue?
Thanks for reading.
after some digging in the code and a discussion with the person in charge of this feature, it appears that webdav is not supported by http inspect. the http method propfind is rejected by http inspect.
This is not considered a bug.
But I believe we might add it with a feature request.
