I believe that the PIX firewall needs to be made aware of sqlnet
traffic so that it can mark the sqlnet packets on the way through with
appropriate ip addresses (if you are using NAT).  This is all from
memory and I'm on a course until Monday - if you don't get useful
responses by Monday drop me a line and I'll see if I can dig out our
change document that did this on our PIX firewall.
