BTW, nmap -iflist shows that I'm the type of interface is ethernet and nmap
worked fine at when my PC was at a different location.  This is the first
time using it in my new location.

I meant to say also, that a search on this indicated that this error was
mostly in older versions.

A couple of discussions about misconfigured gateway addresses (mine is
correct) and possibly something with using a Cisco VPN (we're not using, I'm
on the LAN).

But nothing else yet....

All, what would cause this error when scanning between locations?

nexthost: Failed to determine dst MAC address for target x.x.x.x
QUITTING!

NMAP works fine when scanning my subnet, but the minute I scan between
locations (i.e. crossing the router), I get that nexthost error.

What is or isn't set correctly in my machine and/or on the router?  (BTW,
I don't have access to the router to view the config)

Thanks.
