I discovered I am behind Carrier-grade NAT with TOT Fiber. Does anyone know if they hand out IPv6 ip's, or perhaps a public IP if requested for their FttH users. I am looking for something similar to AIS's system to at least get port forwarding to work (https://www.thddns.net/login).

 

I thought it was the supplied fiber to Ethernet modem/router (ZTE F660) doing the blocking. After having TOT put it in bridge mode, looking at the IP address, and playing around with netcat I can see its CGN. :-(

I wish this stuff was in bold print on the brochure.

 

TOT has the most IPv4 space in Thailand. If they use CGN means their IPv4 is depleted.

Ask customer service to get out of CGN. 

We are on TOT fibre and seem not to be on a CGN (router external IP is the same as that reported by 

http://www.ipaddresslocation.org/).

 

As noted by @muratremix call them and ask to be taken off the CGN.

 

Thank you for the replies. Will do and report back.

Called, they changed it. I'm a happy camper again. thx
