I feel like I'm missing something and as such have some questions.

Why are you using a firewall instead of leveraging the web server's
ability to filter by IP?

Okay. (Additional) security through obscurity. Sure. I do similar
with various things.

Why? I feel like this voids hiding the Mailman Web UI on an alternate port?

Or is this purely so that you can protect the Mailman Web UI via the
firewall without impacting other web resources running on the default ports?

I've not messed with GeoIP filters in a long time. I don't know how
IPTables' GoIP feature set compares with Apache's / Nginx's GeoIP

I can see a VPN for corporate users. I think it's a high bar for most
public mailing lists. Maybe not for the (few) administrator(s).
I feel like port knocking is a REALLY HIGH BAR for most public mailing
