DNS & IP Spoofing Error Messages

[Scott O'Connell]

I've been having a problem where my firewall has been logging IP spoofs from
a dual-homed BIND 8.3.4 server on FreeBSD.

The problem appears to be that some queries are coming from the SOURCE
address of my public side, and are being routed out the private interface,
and vice-versa.

Is there a document available that details configuration to keep this from
happening?

Thanks in advance,
