How do I open port 27015?
I'm trying to open port 27015 on Win 7 Ultimate. 2ip.ru writes that the port is closed, when the antivirus (Kaspersky) is turned off. IP-dynamic. 2ip.ru and the command nslookup in the command line gives out different IP, respectively, the IP is internal (correctly determined?). Everything is open in the firewall. I called the provider, they say that they do not close any ports except for the 21st. So how do I still open this port?!

Probably you are behind the bridge, so the port will be closed from the outside. There is nothing you can do until you can organize a "white" ip address.
Order a dedicated IP address from your service provider(usually $ 0.5 - $ 1 per month). Usually, in Windows, you just need to confirm the request when you first start the server to access the network.
Try to exclude errors, check the port openness in the local network, make a reconciliation from the network between computers. If everything is fine, look at the settings of the braundmayer, as well as whether this port is occupied by someone, if the router is just a proxy. On Linux, this is done in one line.
