sure. the external IP doesn't appear on any interface on the machine,
so it won't get advertised solely because it's in that file.

nor is vos changeaddr correct, because, no, the server doesn't have
that address.

undo vos changeaddr; then, instead, modify the NetInfo file so the
external address is prefixed with
"f "

if the external address were; and restart the fileserver.

see if it's still true after the server is correctly configured.
