Cellular Network Port Forwarding

[ghazranka]

I'm currently using a t-mobile sim card in an netgear lb1120 router. My understanding is that t-mobile designates private ipv4 addresses which makes traditional ways of port forwarding through the router useless. How would I go about port forwarding in this situation?

T Mobile uses Carrier Grade NAT. So your kinda boned. Im not sure if a VPN solution would work, but speeds would not be great. At least at my home I get about 25 Mbps. However I have seen T Mobile speeds as high as 100 Mbps in other areas. But VPN's can and do slow down your internet speeds.

Gaming VPN?

 

Why do you need portforwarding?

Alright so I'm boned in the port forwarding department. I've done some tinkering and figured out that I can use IPv6 to do what I need but I've hit a snag. When I connect my desktop directly to my lb1120 router IPv6 works perfectly and I can ping it from an outside connection. However, when I set up my network like this: lb1120 -> netgear r6400 -> desktop IPv6 no longer works. I've set up my R6400 IPv6 using automatic configuration but no dice.

IPv6 its a pain in the ass. There are multiple ways ISP's can set this type of connection up. You need to check to see if T Mobile published these settings some where.
