My need is to block IP only for the cloudron login page (my.mydomain.com).
I'm unfamiliar with iptables.
I searched and read some pages on the web, so I'm sorry if I ask you a pointless question.
As far as I read, iptables settings looks it affects all the Linux VPN.
So my concern is whether I will shut the public accesses to my websites on LAMP and Ghost apps when I execute
sudo iptables -A INPUT -s xxx.xxx.x.x -j ACCEPT.
I know this forum is not about teaching tech stuff - but I'd be happy if somebody can guide me through.
