Yes, I know that I did not include ipsec info; but, I fail to see any
relevancy.  Isn't martian-ness independent of anything ipsec?

What I see here is a valid public address trying to come in the publicly
addressed external interface of a router.

My question, I feel, remains valid: How can this be considered martian?

Clearly, in order for me to understand this, I need a better grasp of
martian-ness.

Pointers?  Docs?

Dare to fix things before they break . . .

Our capacity for understanding is inversely proportional to how much we
think we know.  The more I know, the more I know I don't know . . .
