Hi Arthur,
I think it's possible considering you don't want any return code. You might want to read up on something called port mirroring or clone pooling. Here is solution link to the Ask.f5.com site that talks about it.

The technique they talk about is more less meant to for dedicated intrusion detection system (IDS) or sniffer device for troubleshooting purposes, but I suppose in theory your database can pick up the packets but never really process the return traffic.
I hope this helps
