Hi Fellers
I have a weird situation at firewall.
I have been deploy a mariadb container on server.
$ docker ps
d65e7fd9a65d | mariadb:latest | "docker-entrypoint.s…" | 3 months ago | Up 6 weeks | 0.0.0.0:3306->3306/tcp | mysql
As shown it is reachable from outside of sever.
$ nmap -Pn -p3000-4000 [SERVER IP ADDRESS]
PORT STATE SERVICE
3306/tcp open mysql
but when i check yast firewall, there is not such opened port in there but my application can connect to db with server ip address and port 3306.
$ firewall-cmd --list-services
ssh dhcpv6-client http
I want to restrict access to database for just one ip address can access to it.
Can you explain why firewall could not see this port?
