[HH#165436] Need to stop UDP connections and QUIC, is it possible?

[HelioHost]

VPS number: 10, VPS ID: 542

Hello everyone,

we need to block UDP communications on our server, specifically on port 443. Is this possible? Can we do this ourselves, or will you handle it? This would help us force the use of QUIC and HTTP/1.1 or HTTP/2 in our application.

Thank you,
Fabrizio

It looks like you're using Ubuntu 22 so you can use the ufw command to allow/block access to certain ports and IPs, etc. Here is a guide

Thanks for the reply, unfortunately we are not expert enough to
configure this. Is there a Helio Host support that can help us?

Sure, what ports do you need open other than TCP on 443 for https and TCP on port 80 for http and TCP on port 22 for SSH?
