I have a question about whether something is 'possible' by default or requires additional setup.
Lets say I have two systems behind a firewall and they are in the same domain and subnet. System 1 has IP 10.1.1.2 and has IIS installed (aka listening to port 80). The other system is just a normal system that has outbound internet traffic.
Should system 2 (The outbound traffic system) be able to hit the external ip and have it redirect to the server running IIS without having to modify any host file or NAT setting?
Here is a topology of what I am taking about:
Should the computer system at 10.1.1.1 be able to hit (either directly with the IP or through a registered dns like my.domain.com) the external ip (220.127.116.11:80) and have it 'resolve'/redirect to the internal server located at 10.1.1.2?
