Stopped UFW, use Vultr Firewall

Hello experts
Due the limited RAM of the VPS. I just stopped ufw firewall on Ubuntu and use the firewall of Vultr.

Here is the screenshot setting https://prnt.sc/w0k2ck

Is there any other feature of ufw on Ubuntu that I am missing when stopped it?

Because when use UFW, I also set only few rules like the screenshot above.

I hope will save some amount of RAM while still keep the server secure

Do you think secure this way is an acceptable option like use ufw?

Thanks

Seems like a good idea to me.

I've set the rules only accept port 80 and 433 with source from Cloudflare
and site is still working well. https://prnt.sc/w0vjye

Seems Vultr firewall force all traffic must go over Cloudflare in this way?

Better to stop DDoS?

You may also want to consider allowing your IP, in case you ever need to go direct to the site via localhosts.

I don't have a static IP so I set any source for allow ports, less secure but don't have choice.

But to answer your question on DDoS protection, yes, that looks like a great setup.

@webservices there are dynamic dns services available, and maybe Vultr allows for "allowing" a hostname, vs an IP address. Just an idea.
