A client has a web server that needs to be accessed from the internet.
Its internal IP is 192.168.100.5.
The client connects to its ISP via a cisco router. Behind the router is a Cisco ASA 5505 Firewall (Security).
The ISP has given the client a public IP address block of 81.x.x.0/27.
I intend to NAT the public IP address of 81.x.x.5 to the internal IP address of the web server (192.168.100.5).
Natting is to be done on the Cisco Router.
I have some experience with Cisco Routers and firewalls, so i managed to set this up.
However, while the webserver is able to browse the internet, it cannot be accessed from the internet. I believe i must be doing something wrong.
I have attached the relevant aspects of the configurations of both the Cisco Router and ASA.I have also attached a Network diagram of my setup.
Kindly help take a look at it to see what i am doing wrong.
