Hello, friend!
Generally, the virtual port of the ONT (HG8245W5) is enabled by default before delivery and cannot be enabled by itself. If you cannot access the port of the ONT (HG8245W5), the following situations may occur:
1. The port is a well-known port or a port that is providing services. The port has been occupied and cannot be accessed due to service conflicts.
2. Access blocked by device security
3. The device is a custom version and the port is disabled at the factory.
Thanks!
