There is a 4G router with the ability to connect to a remote VPN server(L2TP protocol) as a client.There are only 3 text fields in the settings: Server, Username, Password.The server is used as the server with static IP on Windows 7, where the VPN server is configured using standard Windows tools.The connection is successful, the router receives an address from the range specified in the TCP/IP settings.The settings are shown below:



The question is, how can a router issue a always permanent IP if it plans to have several more customers in the future? You need a permanent IP to get access to services that are located behind this router, and not behind another router/client.

Write statics on the router with hands from this range.
As far as I know(although I could be wrong) in the built-in dhcp of Windows 7 there is no possibility of such settings as the MAC address.
Well, or alternatively, contact the wrong address, but by name — lift a DNS server, for example.
If you are not satisfied, use the server axis - windows server, ubuntu, routerOS, and the like, where there are necessary functions out of the box.

to get access to the services that are located behind this router
If you will use Windows 7, besides static, you will need to step on a rake with port forwarding through NAT, this also done in Windows 7 rather obscure, inconvenient and not flexible way.
  • And in which section of the web interface of the router can statics be written and under what name can it be?
    Or should it be done manually through text commands? I found such a thing in the manual for the router, it is not it"the CLI or Comand Line Interface allows you to enter and execute commands in the terminal mode of the router." ?

  • [[ssman]],
    in which section of the web interface of the router can statics be written, and under what name can this be?
    is usually called DHCP. It depends on the firmware, for example, in xWRT this is a network - dhcp - Static IP addresses(for DHCP) - press the add button and that's it.
    In Mikrotik - IP-DhcpServer-Leases - click the plus sign and add the desired poppy and aypishnik.

  • I found the following thing in the manual to the router, it’s not the CLI or the Comand Line Interface that allows you to enter and execute commands in the terminal mode of the router
    CLI then the command line interface.
    So that you don’t have to wander around the menu and click incomprehensible buttons, you can simply enter the necessary command in the terminal.Study the commands of this router and go into battle.
