I have setup a webpage written in IIS. The webpage allows contractors outside our coporate Network to login and fill in forms that i can process. I have a Cisco router sitting on the edge of our network. I want to secure this Cisco 1800 router so that it can only be used for accessing this particular web server page and nothing else. I want the Cisco router to be able to go out onto the internet - unrestricted. But from the outside world in - it can only hit this web server.
I have tried to setup the NAT on the router. I can successfully go out to the internet but cant hit the webpage coming back in. I have setup an Access List but it is obviously not quite right. Could anyone take a look at the config and see it they spot anything obvious.
In the mean time i have just installed a normal netgear router and used that instead until i get this Cisco 1800 router correctly configured. Any advice is welcome.
you need to have the dns service so that you can have a IP to name mapping. I don't know whether you have static IP address or not. if you have a static IP address then you can ask your service provider to add the dns record for your website onto the dns server. if you don't have static IP address then it will be difficult and you might require the dynamic dns service.
you can only test your webpage when you will be using the internet other than in your office. you can type your service provider IP address into the browser when using the internet outside of your current internet connection.
to get the current ip address of your service, you could type the command 'sh ip int brief'.
