For UDP you use ICMP and TCP uses resets


The readme.flexresp and readme.inline might help clear a few things up,
along with the online manual

Subject: [Snort-users] Error on new Rule

On the below new rule, I added the react:block for the FlexResp feature
of snort.  


alert udp $HOME_NET any -> $EXTERNAL_NET 41170 (msg:"P2P Manolito Search
Query"; content:"|01 02 00 14|"; offset:16; depth:4;
reference:url,www.blubster.com; reference:url,openlito.sourceforge.net;
react:block; classtype:policy-violation; sid:3459; rev:2;)


I get the below error:


ERROR: Line /etc/snort/local.rules(28): TCP Options on non-TCP rule

Fatal Error, Quitting..


Does FlexResp only work on TCP rules and not UDP?
