Hi. I just got connected with a new service T-Mobile Home Internet which uses an LTE Gateway. The gateway supports NAT. But, I cannot get my private mail server or remote network access to work using your service. It's possible that is because the router has an external IPV4 address that is different than the one reported by your website when I connect from inside that network. The router does have a IPV6 address also, but I haven't been able to get that to work, either. Is this possible? The tech at T-Mobile for this service didn't know what DDNS means, so couldn't help.

Thanks,
Gregg Kaloust
