I can access the management page from any browser but the username and password is not accepted.
Firewall is OFF, I can PING, Page Loads No Problem. I can Log in no problem from eth0. I just can't log in from the cellular public IP. I also tried with firewall ON (I opened HTTP), same issue. USER AND PASSWORD NOT ACCEPTED. The unit is in passthrough mode with HTTP/s and PING pinholed.
It is the latest firmware. I was able to log in from the public IP with the original firmware that was on it but updated to get passed a few bugs.
