do you use firewalls on servers?
servers are usually behind router/firewall at home, so you can avoid firewall on server.
but if you have VPS in cloud then server is reachable from internet, it has static IP.
also I think that firewall should be running on home server too. you never know which member of family get some virus / malwatre on his device
I am runnig mix of services on my home servers, some of them are running in docker container. And managing docker networks with firewall is sometimes bit complicated.
I am using shorewall but thinking about change to firewalld.
what do you think?
