Asked by support2bd6f6efeefcc3c0033
not sure how to do this been looking for hours and I do not see 1 example …I would think this to be a normal frequent question. I only need my website which is hosted on another place to access my digitalocean droplet. I am sure it can be done easily enough in the digitalocean fire wall but I have had zero luck with my testing?

Hey there @support2bd6f6efeefcc3c0033,
Our product docs have a great section on creating custom rules in our cloud firewall. You can use these to allow traffic through a specific port or from a specific IP.
In your situation, if you wanted to permit all traffic from a single IP, simply create the custom rule as the custom type with the port range left blank and in the source simply put the IP of the server you’d like to permit through.
Hope that helps! - Matt.
