Ports not open through AT&T fiber hardware yet AT&T says everything open.

I need to have multiple ports forwarded to devices on LAN for a company to SSH into these devices. (Lets ignore that a VPN would be a better way to handle this for the time being.)

I have deployed this setup multiple times across the country using UniFi gear. This setup is no different aside from the ISP being AT&T dedicated fiber. Same hardware, firmware, LAN, forwarding rules. Everything the same.

But I can not reach the devices on the internal LAN.

I am not quite sure what to ask the AT&T support to do at this point, they have stated

"This internet router is not blocking any ports for the Public LAN block "
