I remember issue where some proxy was caching stale copies of daily.cvd...

If you don't want to let your file server access the internet
directly, did you ever try setting up a proxy server (and configure
freshclam to use it)? That would solve the direct access dilemma, and
also cache cdiff (and other) files locally to save bandwidth.
