optivision router bsnl port forwarding need help

[sloj]

Oh, your region has been moved to CGNAT too. If it's a v4 address then nothing you can do from a v6 address. I guess static IP is the way forward.

@sloj , so they will ask a price for static ip ? any ideas

 

[sloj]

Yup, static IP will come at a price. Don't know how much. Might be mentioned somewhere on their site.

 

[MEGAN]

@Protector is your ip static ? is it cgnat ? pls kindly answer , thanks

 

[Protector]

@MEGAN No. My IP is not Static. I'm not sure if I'm on CGNAT but i'll post my tracert here.

Your IP is not CGNAT @Protector.
Most common BSNL Public IP (Non CGNAT) IP series are 117 and 59

 

[Protector]

Oh! Thanks for the information.
My IP address are usually 117.x.x.x or 61.x.x.x
Sometimes it connect to 180.x.x.x (MTNL) so I usually restart and it goes back to 117. Most of the time and 61. Sometimes.

As per RFC6598 RFC 6598: IANA-Reserved IPv4 Prefix for Shared Address Space CGNAT IP range is 100.64.0.0/10 subnet (100.64.0.0 to 100.127.255.255).

trace route google com went to onu ip adress then to ipv4 ip address 100.*** which is a cgnat ip adress --- then request timed out comes after that. mm does it mean thse cgnat ip adresses dont open these 80 443 etc ports ?

What IP address do you see on your ONT interface? In CGNAT you don't have control over the ports, ISP may or may not do that at your request.
