I've been working with my ISP to open some ports on my JioFi 3 MiFi device (a pocket-sized WiFi router that runs on a SIM card, often locked to the SIM provided by the company that makes the router.)
Recently Jio have launched their own MiFis devices, using UDP port 11155
. All goes fine, I can just go and type in my local IP, the port range, and select the protocol and the port should be open, except that it is not.
Also, by default, my MiFi shows an IPv6 address as my public address, so I disabled IPv6 to only have IPv4 to work with.
The WAN IP, as shown on my router config page, is different from my Public IP as reported by Google searches and Whatismyip.com.
The proxy test on my Whatismyip.com detects no proxies. My ISP can set up port forwarding perfectly using the same device and procedure that I am using. But since my public IP and WAN IP don't match, I have a reason to suspect that the problem is on the ISP side.
However, could it be possible that something on my end is blocking my connection? I have no additional routers. Also, I have an almost fresh installation of Windows 10 Home. I'd like to be sure that there is no issue on my end before I rant my ISP again.
