Cannot access web site from external, works ok on LAN
Hi
I have set up a web server as a training aid to learn IIS and DNS.
I have registered a domain name and pointed the NS to my web server.
I have also configured my netgear modem to forward port 80 and port 53 to my web server.
I have set up the DNS server with a primary zone that and a host (A) record that point to the ip address of my server 192.168.1.3.
I have then set up IIS so that it picks up the host header of my domain name from 192.168.1.3.
All this works fine if i type my domain name into IE on the LAN ( i get my web site)
But if i type the domin name in on an external computer i get the following.
The Web site cannot be found

Try to change the Local IP 192.168.1.3 to the global IP, which is provided by your ISP, you can find that info by login into your netgear router

Are you refering to the Host (A) record and the IIS web site properties
Hi,
How the DNS is configured for the website? Are you pointing to a public IP or private IP? External users cannot access your web server using the private IP address.
If you are hosting your domain dns with external dns server (e.g. your ISP), then it should point to the external IP address. If you have a firewall / router that is capable of NAting IPs then you need to NAT the external IP to the internal IP.

I have the name server of the people hosting my web site pointing to my external IP address.
Which then forwards the requests to my router, i then forward port 80 and port 53 to my web server.
I then have my web server set up to use my dns server, which then have to primary zones set up www.mydomain.com and mydomain.com which which use a host (A) record that point to 192.168.1.3 which is the ip address of my web server.
I am not sure if this is the correct way of doing things???
thanks for your help so far.

Hi,
I could be that you are not getting the right IP address from DNS server. Can you run
nslookup www.mydomain.com and see what ip address you get?
