When reverse proxying (nginx) from a separate machine from neko, how should I handle UDP ports?

I have a working neko setup, reverse proxied as per this example configuration (albeit with two lines added for ssl_certificate and ssl_certificate_key).

https://neko.m1k1o.net/#/getting-started/reverse-proxy?id=nginx

The nginx service runs on 192.168.0.10, and neko runs on a VM I have for my Docker containers at 192.168.0.20.

However, I realised that despite there being no extra listening/forwarding rules for the UDP ports specified, neko still works seemingly fine.

As a test, I created a neko.stream file so that nginx would handle these ports. Whether I enable this or not, both nginx and neko again seem to work, with no difference (as far as I can tell).

Should I be forwarding these ports for a better experience?

And if I should be, are there any extra stream{} options I should be including? (e.g. ssl_certificate)

As an aside, love this piece of software! Thanks to all the contributors for their great work
