Unable to access my local web server via WAN-IP (provided by ISP)
I was trying to build a small experimental server
- I have set up windows to use internal static IP 192.168.1.10
- I have forwarded the port number from my router to redirect all requests on port 80 to my PC
When I try to access 192.168.1.10 the web server replies to the request but it no replies when I try to access it through the WAN-IP
NB : I've disabled the firewall for both my PC & Router
You router's WAN IP is 10.128.40.X. Unfortunately 10.0.0.0/8 ("10.xxx.xxx.xxx") is a private IP range and therefore your IP belongs to your ISPs carrier-grade NAT (CGN) - it's not a public IP.
You can check this yourself by testing if your router's WAN IP matches you public IP (whatsmyip.com etc.). If not you are behind a carrier grade NAT. If so, you might be able to access your server via IPv6 (assuming you get one assigned by your ISP and your router supports it).
If IPv6 does not work and you still want a public IP, there are several work arounds. Easiest would be to ask you ISP to provide you with a public I. Or you can use a VPN service or proxy which provides you with a public IP (or use a remote tool):
If you don't have a public IP address you will need to use a proxy or a VPN service (e.g. use AirVPN and setup a port forward). There is no way around that for "direct access" over the internet if you are on CGN. If you don't need "direct access" you could login into a local machine on your network via a remote tool (e.g. Anydesk) and access your Server from there.
