although i can't say for sure.............
logically, the packets would have to be decrypted first before they could
be authenticated, because the router would not be able to compare the
encrypted key-string to what it has in the local data-base or where-ever it
is that you are authenticating.
but logic, of course, isn't always right.

  In a BOTunnel Source and destination must authenticate before encryption
takes place, now
  at the destination host, which security procedure is usually done first-
decryption or authentication? Any good white papers on this!
  Much appreciated.
  Thanks
