If you mean access the configuration on it remotely, that is not possible. If you're trying to access a device on your home network remotely, that'll be under the settings though some port restrictions will apply for incoming connections.
No idea if the Actiontec supports this but try forwarding an external port such as 8888 to port 80 on the routers IP address. Those routers are extremely locked down so I wouldn't be surprised if this doesn't work. Be careful with this though, you are exposing your router configuration page to the entire world. If your password is compromised, or a flaw is found that can be exploited, they will have complete access to your internal network.
