I have asked this question before, but never got any confirmation from anyone actually using the Pace (ATT) 5268 router with Smartlink. I am looking for someone who is actually using this particular router with Smartlink.
Reggie, I just signed up for ATT fiber and the gateway is a Pace 5628ac. I found that this gateway does not recognize all ip addresses connected to the LAN. This makes it impossible to forward ports through the firewall. I called ATT customer service and got a knowlegible person who admitted to the problem. Remedy new and different gateway on the way.
