BSNL NAT Type Strict

[Gokul Kannan]

@Pradhuman Yes, it is good not to share the entire IP address, can you share the first two octets of Internet interface IP to check if it is public IP

 

[WieldyBinkie]

Strange. Never seen type 3 NAT on BSNL

 

[Pradhuman]

For the voice - 10.115.......
For internet - 117.220.....

@Pradhuman NAT type: Strict for Warzone | BSNL Bharat Fiber

 

[Pradhuman]

I have tried UPnP, Dmz, firewall settings, nothing is working

 

[GR2]

I don't have the option of nat configuration like nat type 1,2,3,4 my firmware version is old i think it is 1.10 and the guy who has the option of nat is 1.30, how do i update it? Will upgrading my firmware reset network configuration?

 

[GR2]

@Pradhuman I don't think you can update the ont manually and also updating doesn't reset the configuration.

 

[Pradhuman]

then how can i use port forwarding? i think this can help at last because i have tried all the other things

 

[GR2]

@Pradhuman Yes, you can port forward because your wan ip is a dynamic public ip.

 

[Pradhuman]

Can you tell me how to do that with my router, i don't know the start and end port and ip stuffs

 

[GR2]

@Pradhuman I don't know because i am not on bsnl bro. @varkey, @vignesh_venkatesan , @Kick933 can you guys help him?.

 

[Pradhuman]

This is NAT configuration on my router, i dont know what to fill in these blanks

 

[vignesh_venkatesan]

Try turning on upnp.. this might solve the issue.
If not you can manually configure Port forward entries.
Those ports change based on the application.
What are the games you play ? Which is affected ?

turn on upnp in router.
Do network reset on pc. after restart, shut down router & pc for 2 mins.
start both .
In cmd type netsh interface teredo show state
You should see something like this:
netsh interface teredo show state
