and do you have false alert if you add ip_proto:46; on this rules ?

I don't think that's possible, is it? This rule is looking at the data in a packet *not* at the IP header. You would need to sort that out first, and I don't think snort has that ability. Or is the data going to include the protocol somehow? The tenth byte of the IP header would tell you what the protocol is, but I don't think snort has rule syntax that looks at that. (I could definitely be wrong.)
