Anyone knows what this could be?

Yep.

Could you tell me some more, please?

I hope it isn't evil, I have a lot a these packages coming.
Depends.  Check out:  http://snort.sourcefire.com/docs/faq.html#3.14 for
info on what's going on and why.

Well I tried running with the -z est flag but the alerts doesn't change, I 
guess that the checksums for the incoming packages doesn't match or something 
like that.

Before my time here, the server was configured with stronghold where the 
proxy funcion was enabled. Now we have removed this almost a year ago, but 
there are still requests coming. Could that be the cause of what I am seeing?

Another thing, the ports database that was on the snort site some time ago 
has vanished. Any chance of putting it on again?
