I have a new fiber going to a USG-Pro-4 with a local cloud key. “I did not buy this, it is what they had”.
AT&T gave me this:
IPv4 WAN IP Address: 12.88.NNN.92
IPv4 CR IP Address: 12.88.NNN.94
IPv4 AR IP Address: 12.88.NNN.93
IPv4 WAN Subnet: 255.255.255.252
Routing : Static
IPv4 Default Gateway: 12.88.NNN.93
LAN Information
IPv4 WAN IP Address: 12.97.NN.0
IPv4 Subnet Mask: 255.255.255.248
IPv4 Usable IP: 5
Told me to use 12.88.220.94 on my WAN interface. I have internet service but I am not able to forward any port, ping from outside world, setup ddns service. I am thinking that I am double NATed or that I should be using one of the static WAN addresses 12.97.NN.N . Talking to AT&T for hours and a little useless. They can see the USG on their interface. I can not see it from the outside. Anything coming from inside of the network works but nothing from the outside.
Thank for any help…
