Currently, I am testing T-Mobile 5G Home Internet. Here is what I found while I am doing testing:
1. CG-NAT, I am getting 192.168.12 IP on my router WAN
2. NAT444, NAT after NAT, even whatismyip.com gives me a public ip which is the tower public ip, not my modem/gateway Ip.
3. On my Asus router, I turn on IPv6, so I have a public IPv6
My setup:
1. Internet <-> T-Mobile (modem/gateway 192.168.12.) <-> Asus router (192.168.1.0/24)
2. I have Ipv6 on my router, which is a public 2607:fb91:82ae:1493
3. I have OpenVPN server setup on the router. (I tested by access 192.168.12.x from my internal network which works, but it doesn’t work when I use the public IPv6 Ip)
4. I have firewall disabled to make sure things work first
Goals:
1. I can access my internal network from a public location, so I can get files on my harddrive (attach to the router USB port)
2. Access other web which has region check and I was oversea
Questions:
1. How may I OpenVPN into my router from public so I can access my network resource?
2. Any other suggestions?
