Generally the DPD signatures trigger only if there's something looking
like the assumed protocol on either side of the connection; that's to
avoid attacks where a client generates tons of bogus traffic without
any server responding.

A more specific answer to your question depends on what exactly
"unanswered" means. If there's some reply from the server at all,
maybe we could tweak the DPD signature to take that into account.
Alternatively, you could add your own custom DPD signature that
matches on just client side traffic if that's what you prefer.
