Hi Shawn,

 

 

I'd guess it's traffic that is hitting LTM but on an IP which isn't defined or enabled. If you're doubting that the traffic is hitting LTM, you could run tcpdump on 0.0 or eth0 filtering on the source IP to see:

 

 

tcpdump -ni 0.0 -Xs0 host 10.73.0.105

 

 

216.18.209.131 seems to be an LA colo address serving a default apache page. Odd...
