It would be helpful if you said which of your interfaces define the LAN and WAN.
In many cases this is caused by having a machine that is IP numbered in one network but plugged into the switch or interface for another IP network.
So the question is where is the machine with IP 192.168.1.69 ?
I do find it interesting that the MAC address and IP address involved are identical to those contained on this eleven year old page:
