We have leased a routed block of public IPs (example: 188.8.131.52, 9184.108.40.206 etc.) that will be used for our 10 public web servers (eventually). These servers need to be placed outside the corporate firewall and should be accessible without using VPN. All these public IPs are on a WAN subnet that is different from subnet of router's WAN. The desired result is that if anyone on the internet accesses 220.127.116.11 or 918.104.22.168 from their browser, that request should hit the respective web server. Can you all please suggest how should the router be configured? Do I need to set up port forwarding?
I understand that all routers are different but a theoretical explanation will suffice. I will be happy to provide more information, if required. I am also open to suggestions to buy a specific make/model of router and/or other networking hardware to resolve this situation.
UPDATE 1: My previous ISP had given a block of public IPs that had subnet mask same as the router's subnet mask. Under that setup, I was able to use a switch between modem and router and connect all my web servers to the switch before hitting the router. So these were truly public servers having their own IP and required no VPN. I'd like to implement something similar with the current ISP that gave me two different subnet masks.
