We are having some issue accesing, from our LAN, to a web server situated on the same internal network through our public address. We are trying to do so, since we use a program with a hyperlink to that web server and, we can use it making demos on our LAN or on a customer's site (no DNS server available on our LAN).
We have a Cisco 837 ADSL router and we have the NAT configured. From the Internet we haven't got any problem on accessing the http port of the server. But, when from our LAN we type http://X.X.X.X (where X is our public IP address), we do not receive any response (if we activate the "ip http server" on the router, we access the router web page). This is what we have configured:
ip nat inside source static tcp 192.168.1.2 80 X.X.X.X 80 extendable
ip nat inside
ip nat outside
What are we missing? Should we use "ip nat inside destination.."? Is it possible to do this configuration?
Any suggestion will be appreciated!
THANK YOU VERY MUCH IN ADVANCE!
