Performing a packet capture on that interface would provide a lot of insight into what packet is being received, and perhaps why it is being discarded. Data travels on the internet in small pieces; these are called packets. Each packet has certain metadata attached, like where it is coming from, and where it should be sent to. The easiest thing to do is to look at the metadata. Based on rules, certain packets are then dropped or rejected. All firewalls can do this. It is done at the network layer.

I don't have a way to view the spoofed packets going out, but I can see the incoming packets getting corrupted and dropped by the guest. Determining Packet Loss on WAN Uplink. If packet loss is observed on the WAN uplink, the next step is to determine if the loss is on the MX or on the ISP side. You can determine which interface is experiencing less by taking packet captures on the LAN and Internet interfaces of the MX security appliance. A packet might be dropped at a point in the network stream for many reasons, for example, a firewall rule, filtering in an IOChain and DVfilter, VLAN mismatch, physical adapter malfunction, checksum failure, and so on. You can use the pktcap-uw utility to examine where packets are dropped and the reason for the drop.

Wifi is less reliable than wired Ethernet, and some packet loss is normal. It means "packets dropped because they came in too fast for dumpcap to save"; the packet capture mechanisms that libpcap/WinPcap use (dumpcap, like tcpdump and many other packet-capture programs, uses libpcap/WinPcap) have a buffer into which packets received from the network are dumped, and if that buffer isn't emptied fast enough by the application, packets that arrive will be discarded. Aug 15, 2012 · To log both the incoming and outgoing dropped packets, add the following lines at the bottom of your existing iptables firewall rules. iptables -N LOGGING iptables -A INPUT -j LOGGING iptables -A OUTPUT -j LOGGING iptables -A LOGGING -m limit --limit 2/min -j LOG --log-prefix "IPTables-Dropped: " --log-level 4 iptables -A LOGGING -j DROP Depends on the context.
