Note: Remember to make a copy of all current ip settings before proceeding.
From ATT's page:
the bold text says: "Note: Remember to make a copy of all current ip settings before proceeding."
but does not give a link, nor explain how to make that copy.
Is this copying done by causing my AT&T Arris NVG599 device to make one via some function like "Export"? Or am I do make a handwritten note of the current ip settings? And which settings and why would using passthrough change them, please?
