2 public IP one interface

RouterOS General
1

Hi, good day…

We have 3 Public IP given by ISP.
I set up a Mikrotik router box with 2 interface card,
one interface for a public (internet) and one for internal LAN.
I want to add a web server in one of computer in a LAN and redirect request from another IP public to that computer.
The problem is that the router already has its public IP and I want to set up the web server’s public IP address different that router’s public ip address.
can I just add the address to public interface and set up nat?

Hai fren,
my answer is yes and possible will make as you want.
other your public address must nat and mapp to local one and put it, just talk to your router and broadcast as itself.

you can use dst-nat to map 1 public IP to 1 local IP Address.

go here:

and see what possibilities you actually have.

it is usually nice if your web server is accessible only to port 80 from outside world, and all other services (that usually are there) are accessible only from local area network. (somehow feels more secure for me)

Thanks for all the responses.

I have setup my router using 3 interfaces :

  1. Public
  2. LAN
  3. DMZ
    My web server is on the DMZ network.
    I added the IP address of the web server to interface Public of the router, then I just redirect
    the source and destination address from and into the DMZ servers.
    The setup works well so far.
