The original post is over a year old now. Has T-mobile fixed the problem yet? I have a 4g sim with a netgear modem. I can confirm that incoming IPv4 ports are blocked and natted. I have not tested IPv6. I have looked into VPNs. but the majority of them don’t allow port forwards, and the ones that do are cost prohibitive. Cheaper just to stay with cable. My sim is prepaid, so if they haven’t gotten this working by the end of the billing cycle, I’m going to assume that they don’t possess the know-how or technology to provide competent internet service.
I just got a 4G modem with a hotspot sim. It worked great at first, but then I figured out that nothing could connect back in. I’ve read some of the posts above and it looks like some people have gotten around the problem with VPN. I understand that the IPv4 addresses are scarce and this is behind an IPv4 NAT, so we never get to see the real IP address.I was wondering if they could just assign everybody a static IPv6 address. There is no shortage of those. I think I could probably work with that.I got this as a replacement for cable. So its starting to look like I’ll have to call the cable guy up and apologize for all the nasty names I called him.
