"not host 217.x.x.x" will exclude packets where 217.x.x.x is either
the src or the dst.

run snort like this:
snort -i ethX -u snort -g snort <more options> -l /varlog/snort not
host 217.x.x.x


If you use /etc/sysconfig/snort, uncomment the #BPF line so that it
looks something like this:
BPF="not host 217.x.x.x" and restart snort
