snort upgrade and odd logs

i have just upgrade snort from 1.8.6 to 1.9.0 along with all the oppropriate rule files
the upgrade went fine and i created a new snort.conf file.but what i have seen since the upgrade and i cannot resolve is traffic that is classed as internal is appearing
in the log files and within acid. i have set ( and these are examples only) var HOME_NET [192.168.1.0/24, 192.168.10.0/24] var EXTERNAL_NET anywhat i am seeing is what the system is reporting as port scans coming from webservers in the 192.168.1.0/24 address space to hosts outside. snort is reporting that these portscans are being done from port 443/53 amongst other ports. now port 443 is being used for ssl on these same machines. plus i am seeing smnp traffic that is talking between hosts on both subnets. this traffic should be there but
according to the rules as above i shouldn't be seeing it.i have checked the rule for snmp and it states that anything from external -> internal
i have scanned the machines for a root kit and haven't found anything. all of these machines are behind a firewall that only speciffic ports open to the hosts.
any ideas? baz ------------------------------------------------------- This sf.net email is sponsored by: viaVerio will pay you up to $1,000 for every account that you consolidate with us. http://ad.doubleclick.net/clk;4749864;7604308;v? http://www.viaverio.com/consolidator/osdn.cfm _______________________________________________ Snort-users mailing list Snort-users () lists sourceforge net Go to this URL to change user options or unsubscribe: https://lists.sourceforge.net/lists/listinfo/snort-users Snort-users list archive: http://www.geocrawler.com/redir-sf.php3?list=snort-users
