Outbound Ports and IPs for servers are randomly changed at every server restart

You use random IPs and outbound ports for connections to servers that changes at every restart. This prevents setting proper outbound firewall rules so we can connect.

I read in a thread here Port help that your "Engineer" Roman said blocking outbound ports is nonsense. That is complete garbage.

Blocking outbound ports is standard practice in the business world, and should be in anyone's home who has any security sense. Why? It is key to prevent possible compromise such as many of the file encrypting viruses. Many viruses will attempt to connect outbound on various ports. Forward proxies with A/V scanning and default deny blocking outbound ports is how you prevent getting 99% of viruses when browsing the internet.

However, Aternos has no set IP ranges and no set outbound port ranges, at least that anyone has provided, so I cannot setup rules to allow connection to Aternos servers in my home network. This needs to be addressed by someone not lacking in common security sense.

What about using a standard range of ports? Isn't that something that can be done?

Alternatively what about allowing a user to select a port range for use on their server?

What about allowing a server to keep it's IP upon reboot instead of always changing it?

Saying you can't provide the range - that make sense if you are using a provider like Microsoft that always gives dynamic IPs. But if that's not the case, saying you won't provide your IP range is silly because you provide your IP every time you update the server's location - even though the DNS address doesn't update, I can see in my firewall the new address. So I could figure out your range eventually - it would just be a bit of work.
