Hey Michael, 
I will give that a try and see if that works.  I have not tried that
combination yet.

@Jeff,
Where are you seeing /16? Did I fat finger something?
I am trying to filter out /24 (255.255.255.0) for both networks.

not net 10.10.0.0/24  and not net 10.30.0.0/24

My bpf file is ignore.bpf and has one line in it::
not net 10.10.0.0/24 || 10.30.0.0/24

I have also tried variations of that rule using ! instead of  not...
Using && instead of ||
I have also used the rule across two lines like not net 10.10.0.0/24 &&
not net 10.30.0.0/24 But that also did not work.

I have the bpf file defined in my snort.conf file :: config bpf_file:
D:\Snort\etc\ignore.bpf
I also call it with the switch -F d:\snort\etc\ignore.bpf

Still nothing.  Traffic is not ignored/filtered out....snort still
alerts on it.

Right, and I set up the text file, and snort started and read the
file.
But it didn't filter out the traffic.
And I have followed the examples I have seen creating the file, but it

is not working as expected.

please post the contents of the file and the command line you used to
start snort...
