Hello, I have ufw enabled, how to make it accept connections for a postgres server (5432) on the internet, only to the ip 220.127.116.11, I have already tried this: sudo ufw allow from 18.104.22.168 port 5432 sudo ufw allow from 22.214.171.124/32 port 5432 sudo ufw allow proto tcp from 126.96.36.199 port 5432
but nothing works, what could be the cause?
