Is it possible to throw real IPs into the internal network through a router?

There is a cord from the provider with 5 ip, there is a linksys e4200 Wi-Fi router.
The outer lanyard is included in the router.
1 ip is used to distribute the Internet.
4 others need to be sent further through the local network to IP phones

. Is it possible to do this. Or you need to build an external link through switches to devices that need an external IP of the provider's network.

Any ancient tsiska is able at once. Linux is probably made on some kind of Linux, if there is no graphical shell, then pick it with your hands ... First, look at the DMZ (Demilitarized Zone) option. It's not exactly the same, but it might work. The truth is not the fact that the router supports more than one machine (address) in the DMZ.

Try to set this up in simple Linux on a desktop machine, if it works, then put dd-wrt, openwrt (whatever you like) on the router and repeat what you have done there. I think it should work.
On the question of how - look for the implementation of the DMZ. On home routers, it means one ip outside and one host in the DMZ. If you have 5 ip, then configure according to the template, here you don’t even need to forward ip by itself (the internal computer can have a private address).

You can try through Setup -> Advanced routing. And there set up a route to each of the four addresses (yes, this is a bit incorrect, but it should work). True, each internal device must also have a local address and you need to carefully look at how NAT will behave - whether outgoing traffic will all go under one address.

Excuse me - why does the phone need a white IP? sip works great for nat. And if you want, you can teach the same ddwrt or openwrt to pretend to be sipproxy.

Put a switch in front of the router, and plug everything you need into it, well, or bridge one of the router's lan ports, like ddvrt can do this.
