ISP using CGN.. How to port forward ipv6

1

1

I finally came to a conclusion that my ISP is using carrier grade NAT.

I recently was able to encapsulate my IPv4 to IPv6 using tunnel broker. It was working very fine without any issue. However I cannot port forward or open port or host a small web server through my home network.

Is there any better option available for me to open port and do my study work?

Surfing the net i found a VPS can be used. I signed up for free tier amazon AWS and dont know how to proceed from here. I need help because i'm tired with my ISP and useless IPV4.

You can do one of 3 things:

1) Use a full VPN

  • Costs more, but is simple to use
  • You do not need to manage the remote server at all
  • Most providers focus on normal web browsing, so most do not support port forwarding

2) Setup a VPN from a VPS

  • Costs less
  • Requires you to manage your server, and keep the VPN server running
  • OpenVPN AS simplifies setting up an OpenVPN server

3) Use a service like ngrok

  • Best if you only want to access a few ports externally
  • Easiest option for a few ports
  • Free option changes the hostname each time you connect

I tend to go for option 3, as it is easiest, but whichever you prefer to use is your choice

No problem, I use the free one a fair bit when I just want make demos available from networks I do not control. – jrtapsell – 2017-09-05T18:30:00.630

Full disclosure, I am not affiliated with ngrok, I just think the tool is good, although if they want to send free stuff my way I would not say no to freebies :p – jrtapsell – 2017-09-28T19:28:34.710
