If I use ping currently I am getting about 3% packet loss (it gets worse) but with hping (to the exact same ip) I get no loss? As I understand hping and ping use different methods of sending packets, could this be an indication to where my problem might be (buffering or something) ? Ping -- 290 packets transmitted, 281 packets received, 3% packet loss Hping -- 289 packets tramitted, 289 packets received, 0% packet loss I'm using icmp mode in hping, and sending to the same ip...

What I do see sometimes is a message warning me that its limiting open port RST responses - the unit is under a reasonable amount of load though (but not overloaded). The strange thing is that its open port (not closed). Even if I up the limit though (the messages do stop) it doesn't stop the dropping...
