Well, just to clarify a bit, the RST packets aren't the ones you are getting. You are apparently getting port-scanned. The message just says it won't reply by an RST packet to a SYN going to a closed port more than 200 times per second. I would suggest ignoring all SYN packets going to closed ports. Haven't yet used pf though, so I can't say how exactly to do this. -- (-K JohnNy alias Partial Derivative ∂ [home] http://johnny64.fixinko.sk/ [icq] 338328204 [abandoned] [jabber] [EMAIL PROTECTED] [skype] JohnNy64-konik [abandoned]
