I want to add Ubuntu iptables entries so only the following can access MySQL server on my droplet:
- my Rails app on that same droplet should be able to get, post, update, delete, etc data on MySQL on that same droplet
- I should be able to SSH to my droplet and use MySQL.
What iptables entries will make these secure restrictions possible?
Thanks in advance!
