WAN_LOCAL DROP Packets - I dont understand why the SRC IP is showing my external IP

Hi Guys,

Here is a snippet of the log on drop packets.

I masked the SRC ip with x.x.x.x but it did show my external IP.

ubnt kernel: [WAN_LOCAL-default-D]IN=eth0 OUT= MAC= src=x.x.x.x DST=255.255.255.255 LEN=148 TOS=0x00 PREC=0x00 TTL=64 ID=0 DF PROTO=UDP SPT=59690 DPT=59145 LEN=128

Am I reading or missing something.  I expected the SRC IP to be random internet IPs.

Thanks
