	what we have are connections to external trading partners coming
over ipsec vpn's..these addresses are not part of $HOME_NET so l am trying
to suppress alerts on the traffic that l would not to be classed as an
attack or recce. type but still be alerted on other types...if l used a pass
rule then l may miss a genuine alert..
l have also tried the suppress rule http_inspect (gen_id 119) and still
recieve the alerts...obviously from what l have read and what others are
saying it is something l am doing or not doing..

You don't need the -o flag for suppression to work.  -o is used for
when you have "pass" rules.  Suppression and thresholding should work
without it.

Rule 384 is a very generic "ICMP Ping".  Is this the rule that keeps
triggering or are you trying to supperss ALL Ping events with that
statement?  The reason I ask is that there are many many ICMP Ping
signatures.  Are you absolutely sure that it is sig id 384 that keeps
showing and not other ping signatures?
