Why is there no access (ping) to the ADSL modem via the global white IP address?

Question

Computer networks

What should be configured in the ADSL modem to administer it from the WAN?

Answer 1

If it is really "white" aka bought static from Provo, then only the firewall on the router remains or the Prov stirs up.

Answer 2

The question is removed.
There were times when the wire gave honest white dynamics. Now it's not like that.
Sorry for disturbing. Thanks for participating.
PS: Third day, the representative of the provider (not the first line) for some reason confirmed the presence of a white address and sinned against the modem manufacturer.
