Encrypted connection

I've setup freeTDS 0.82 with encryption=required under the DNS info in the
freetds.conf to a SQL Server 2005 server, with
TDS version 8 and have been using tcpdump to view the packets going from and
to my host machine to make sure the connection
is encrypted, it connects but when I view the TCPDump, I can clearly see the
SQL statement I'm passing and records returned as
plain chars and unencrypted, is this normal?   I thought it would encrypt
the entire connection not just the login, what's weird is if I recompile
freeTDS without the --with-openssl or --with-gnutls, it's still able to
connect even though encryption=required is set.
