I want to create a minecraft server for me and my friends to connect to (port 25565). I already use ddclient, which updates the external ip so that the data sent to the hostname is forwarded to the external IP.
I want to remove iptables because it is not going to help with anything suited for what I am trying to do. Although, if I remove it is there any other way I can forward the traffic through my external IP? - Or would it forward by default? And may I add, I would not like to just set the default rule to ACCEPT all connections because this doesn't solve my issue.
I also know that if I keep Iptables, I will have to set up/modify an init script to update the rules every x minutes for the setup to work which will take even longer? But then I also realise that there for a reason - a firewall: To protect against hackers. Though, my ISP (Sky) does have a firewall that is default to BLOCK all connections, unless the port has been specified; in which I have forwarded the ports that are necessary for my server to run.
Would this be safe enough to run my server behind? And can I remove Iptables?
