[Snort-sigs] Matching question

I have a pretty simple question, with hopefully a simple answer.

I'd like to match a packet that looks like this:
|FF 51 xx 00 01 02 00 00 ...|

That is, starting with FF 51, then any byte, then 00 01 02 00 00, then
any other number of bytes.

This is what I have now:
content:"|FF 51|"; depth:0; content:"|00 01 02 00 00|"

But that's going to hit some false positives.

Any ideas?
