The JioFiber router web interface presents option for port forwarding however it does not work in practice.
The page accepts and saves all the configuration changes you do. Yet you won't be able to connect to the port from outside.

The router also has a DMZ and UPnP options and those do not work either.
Customer care is unable to help ("We have no information about this at the moment")

The IP address as seen from outside is different than what the router shows as its WAN IP. So the router is not directly exposed to the internet. It is behind a NAT/Firewall.

The IP the router sees is 100.XX.XX.XX
IP as seen by sites like whatismyip.com is 49.XX.XX.XX

As far as I know 100.XX.XX.XX is a public IP but trying to access that IP from outside does not work either. So the router is sitting behind a firewall.

This is a major limitation if you want to run any kind of server. So developers and gamers beware.
If you want to make your DVR internet accessible, you can't.

With JioFi (dongle) you could use internet accessible IPv6 address to eliminate need of port forwarding but the Jio Fiber router only allocates local IPv6 addresses. Even if IPv6 worked like JioFi, it would not solve problem for IPv4 connections. So there is no alternative at the moment. You can use a VPN, but it slows you down and has other limitations.

I was planning to discontinue my old ISP but due to this limitation, I might have to discontinue JioFiber instead.

They won't give you the same port numbers on the public IP you request. So, it won't work. They'll give you different ports and map them to your internal network. But you may try.
 
@royalroy Can you please share the external:internal port mappings they gave you. Also are the public ip and the public ip for the ports different?
 
My public IP on the internet is 49.37.52.xxx, but the public IP used to access the ports is 49.44.61.xxx. I am not comfortable sharing the exact port mappings on a public forum. But I'll give you an example. Suppose my internal service listens on 2222. The public Jio IP listens on the port 10000 and forwards traffic to my internal network on 2222.
 
Jio has asked me which port needs to be opened ? what should I tell them
I intend to make my NVR online by using jio fiber. it goes online in an instant while using airtel fiber but with jio it is always offline
BASICALLY WHICH PORTS I NEED TO ENABLE?
Consider me noob. @bhojv74 @royalroy

Only your NVR user manual/or the guy who configured the NVR at your place may tell you that.
 


Yes, the ports on the first image seem like it. You don't want ports 21 and 22, mentioned in the second image, open on your network for security reasons. How do you access your NVR feed - using its app or URL? What URL do you use to view the camera feed?

Also, google what ports your NVR model number uses.
