if in my batch file placed inside of my computer IP and start the server when I test the door says the door is open. When I open the server it usually works more if I try to make the connection with my external IP, the connection is not made

if in my batch file I put my IP EXTERNAL computer and start the server when I test the door says the door is CLOSED

my bath:
RustDedicated.exe -batchmode -load +server.ip ***.**.***.** +server.port 28016 +server.hostname " ||Server teste" +server.level "Procedural Map" +server.radiation "true" +server.stability "true" +server.secure "true" +server.globalchat "true" +server.description "teste" +server.url "Sicherheitskontrolle erforderlich" +server.worldsize "2000" +server.seed 27100 +server.maxplayers 100 +server.identity "40716" +rcon.ip ***.**.***.** +rcon.port 28018 +rcon.password 12345

it is okay to put the external ip in the batch file, the more I am with this problem when I put the external ipcouldn't create server on port 28016 (startup error: 5), can you be my ISP?

 

in this way?
my bath:
RustDedicated.exe -batchmode -load +server.ip 0.0.0.0 +server.port 28016 +server.hostname " ||Server teste" +server.level "Procedural Map" +server.radiation "true" +server.stability "true" +server.secure "true" +server.globalchat "true" +server.description "teste" +server.url "Sicherheitskontrolle erforderlich" +server.worldsize "2000" +server.seed 27100 +server.maxplayers 100 +server.identity "40716" +rcon.ip 0.0.0.0 +rcon.port 28018 +rcon.password 12345

 

still it does not work when I connect appears's message

I want to open a server for all players, not just for me
I intend to buy a dedicated, but I am Brazilian and here everything is expensive.

Then I need to make sure that my server will please the players before buying

 

If you run the server on your own pc you must use 127.0.0.1 as ip. You cannont connect to your own pc with external IP

@Wulf Why are my posts under modded view?

 

Do not worry, a dedicated server will run fine

 

thank you

 

so if i type mt IPV4 IP in my .bat file will it still work if people connect with my external ip?
so "Client.Connect MY_EXTERNAL_IP:28015"

 

Sorry to revive a dead subject here, but what would be the course of action with using no-ip and this then? Given my IP is dynamic, it changes frequently and thus doesn't show up in players' history. Is there anyway around that, or should I just as my players to connect via the no-ip every time?
