Given what you've said about your list configuration, if you set the
mod flag on the Gmane subscription address and not on your actual list
members you should see that posts via Gmane From: a list member will
go directly to the list but posts via Gmane from a non-list-member
will be held for moderation.
This is because, at least in a default Mailman installation, we look
first at the From: header in deciding if the post is from a member and
next at the envelope sender.
In the case of a member post via Gmane, the From: will have a member
address and we will see this as a post from that (unmoderated) member.
In the case of a non-member post via Gmane, the From: address will not
be a member so we look at the envelope sender which is a member and
which now is moderated so the post is held for moderation.

I think that will accomplish what you want. Note that if the only "mod"
address is the Gmane address, you can if you wish set Privacy
options... -> Sender filters -> member_moderation_action to Reject and
set member_moderation_notice to something like "Posting to this email
list via Gmane is restricted to members of the list." The downside of
doing this is "backscatter". I.e. if a spammer posts to your list via
Gmane, the From: header probably contains the address of an innocent
third party so you don't really want to reject the spam back to the
innocent person who knows nothing about it. I would be more inclined
to set member_moderation_action to either Hold or Discard, and if
Hold, to Discard held messages that I didn't want to accept unless
they clearly weren't spam.

Aaahh.. To me, that is a "closed" list whereas a "moderated" list is
one where all posts require approval by a moderator.
