Strange ghost traffic on external interface

Hello,


out of a sudden, I have some strange "ghost traffic" on the WAN interface (see attachments) i can not identify the traffic in the traffic monitor, even iptraf doesn't show me a destination port; 10.50.18.5 is an ip in the WAN but i don't really know if it even exists (not pingable).


Help! :-)
