If you’re on AT&T Fiber with a BGW-320 router, see Changed ISP - No Remote Access with AT&T BGW 320-500 - #3 by FordGuy61. Substitute your server for the WD My Cloud.
Default IP address on the router is 192.168.1.254 (mine, anyway). If you want to change any settings, the admin password is on the back of the router.
