Flags rule option

Hi all, I have the following Snort rule:alert tcp any any -> XXX.XXX.XXX.XXX 1024:65535 (flags:S+; flags:A!; msg:"Local suspicious inbound"; )
This rule matches the following datagram: 09/26/02-15:49:14.256645 YYY.YYY.YYY.YYY:80 -> XXX.XXX.XXX.XXX:24247 TCP TTL:237 TOS:0x0 ID:0 IpLen:20 DgmLen:40 DF *****R** Seq: 0x2ED4C858 Ack: 0x0 Win: 0x0 TcpLen: 20I think that both flags options must be matched in order for the rule as a whole to match. Yet, the matching datagram does not have the S flag set. What am I missing?
