Port forwarded, but can't see the server

Hey there,

with a little help i just got my server up and im able to use the admin commands.
now i want
1. my friends being able to join
2. my server on the serverlist

from what i know i only needed to do the port forwarding?
i did that.. for 28015 and 28016 like described in a other thread (im not running rcon but i added 28016 if i may run it in the future) enabled 28015 on both tcp and udp

afterwards i asked a friend to join my server via client.connect ip:28015 -> failed or server doesnt respond
while im in it, destroying helis...

did i miss anything on my way or?

edit: heres my start bat

:START

D:\Games\SteamCMD\steamcmd.exe +login anonymous +app_update 258550 validate +quit

Start

RustDedicated -batchmode -load -server.ip (my personal ip) -server.port 28015 -server.hostname "Sekkonds testserver" -server.description "this is my first server" -server.maxplayers 10 -server.seed 562315 -server.worldsize 3000 -server.identity my_server -chat.serverlog 1 -server.netlog 1 server.saveinterval 300 -autoupdate

GOTO:START

 

any ideas?

 

Need to allow it in windows firewall as well
