I’ve looked all over the web for a way to turn on remote management for my modem/router combo (model SBG7600AC2), but can’t find that option. Does this model device just not have it? Is it possible that the ISP is restricting me from doing this type of this?

I just want the ability to access my modem/router remotely not having to connect to the local WiFi or Ethernet connections.

I already have DDNS created and set up, but it still isn’t working.
