I’m trying to set up port forwarding on a BGW210 (AT&T broadband) modem. AT&T’s BGW210 port forwarding instructions and the menus look nothing like those in the OpenSprinkler port forwarding instructional video. I see no place to even enter the OpenSprinkler’s IP address. Has anyone done this on a BGW210? If so I’d greatly appreciate any guidance that could be provided.
