HTTP Proxy and DNS

burtoncarl

I use the HTTP Proxy(transparent) and the Content filter

    This can't be the same problem - the first poster said nothing was dropped in the PF log.  Please show us full (not "Live") log lines.

    What version is the backup from?  Is this the same hardware the backup came from?

    Cheers - Bob
