“Cannot Forward” messages

[Pocket_Sevens]

Good day all.  I'm running OPNSense with Zenarmor.  I've been seeing a number of messages showing up on the OPNSense console:

cannot forward sc fe80:2::dea2:66ff: fe60:7296, dst 2607:860:4000:805::200a, nxt 6, revif re0, outif msk0

msk0 is my WAN connection.  re0 is my LAN connection.

I'm assuming it's OPNSense telling me a connection is not possible.  However, I don't have any devices with an ipv6 address starting with 2607. 

Any suggestions as to why I'm getting these messages?

Thanks.
