Reliance JioFiber: Port Forwarding NOT SUPPORTED

#1
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.

Because of the NAT you can't access your router from outside the jio network. But, You will be able to access your router from within the jio network i.e. any device (mobile/fiber) with a jio connection. Lets hope they start rolling out static IP's without NAT.

I don't even need the IP to be static as long as it is accessible form outside. A builtin DDNS client in the router would be nice to have when they do this.

True, even i run a ddns client called noip for my bsnl connection. What we need is for them to remove NAT for Jio Fiber users.
Does UPnP work for your router?

Tried it, didn't work. UPnP would help you expose ports to the router's external interface but if the external interface is itself behind a NAT then it is still not open to internet.

Strange thing is that JioFi (wireless) dongle can support incoming connections on IPv6 but not JioFiber. Not that IPv6 only support is acceptable but that is better than nothing.

BTW the JioFiber router does not support DDNS either.

that is called double NAT, the router you have is connected to another router(which the ISP has) which connects to the internet. So even if you port forward from your router its pretty much useless.

Its not just JioFiber, a lot of ISPs do it, and new ISPs are pretty much guaranteed to do it. But if you really need to host a server, you should not be using this setup at all, home internet is not intended for hosting servers.

I am behind a double NAT and I haven't had any issues with games and there are multiple other options to host servers from your house,
So your "developers and gamers beware" is not really valid. IPv4 is basically extinct at this point, so what do you expect?

Pay more and get a static IP from some other ISP



ninja EDIT : the WAN IP you are seeing in the router is NOT 100.x.x.x, more like 10.x.x.x.

I think you need to broaden your understanding of what hosting a server means. It does not have to mean a free for all FTP server to share movies and porn. A SSH daemon is a server. It hardly consumes any data but it is a server. A MQTT broker is a server. Anything that listens for incoming connections is a server.

JioFIber does not allow incoming connections regardless of whether it is IPv4 or IPv6. Also IPv4 is far from extinct. Some of the hardware I work with has no support for IPv6. I guess all you deal with is home networking gear which has support for IPv6 since more than a decade so no wonder this comes as a surprise to you.

Any way, I am a developer and need to host a server. I like the robustness of a fiber connection, free part is incidental, so your jab about paying for it was unnecessary because I am right now paying for a non fiber connection simply because it supports incoming connections.

"ninja Edit: the WAN IP you are seeing in the router is NOT 100.x.x.x, more like 10.x.x.x."

Fuck your ninja edit. How can you be so sure? Do you have remote access to my router? Or you think everybody else is dumb? The WAN IP I am seeing is 100.x.x.x. not 10.x.x.x

Even my router does not support ddns , i have connected a raspberry pi 3 to the router with the ddns client installed (and a few other things.). Just need to keep it running 24x7 thats all.

guys there no way you can portforward on the Jio Gigafiber router, i have spoken to some1 in their technical department whome i know well and i have been informed that only when the service goes live there will be a full pledge firmware upgrade to the router for now the service is a test phase why the issues. Secondly i too have issues running a server on gigafiber and hence have a hathway 50mbps connection for the same, the issue is more so with SSH and PuTTy
