If so, it wouldn't indicate the response is being blocked, but the request. If the response was being block the icmp message would go to app.southuni.com, which originated the blocked packet. > Vr HL TOS Len ID Flg off TTL Pro cks Src Dst > 4 5 00 05dc 07bd 0 0000 3f 01 1677 192.168.0.2 192.168.0.80 is the ip header of the packet to which the icmp-unreachable message is a response to.
