I'm with you @jonsteinmetz it appears that the LTE Internet service uses IPV6 and I think that an port request is not reaching the LTE/WiFi device. Even with DMZ turned on and pointed to an internal box with open ports, I can see using "ShieldsUP!" by Gibson Research Corp that my public IP address is showing all ports closed and in stealth mode. Reproduction stepsPublic IP: While connected directly to the LTE/WiFi device, look up the public IP address via ipchicken or any other IP presentation service.Port Scan: Scan for specific or all ports via "ShieldsUP!"
