This post is for geeks only...I finally got around to taking some screenshots of the various more interesting status and configuration screens inside the U-Verse residential gateway router. The router is a 2-Wire 3800HGV-B in case you are interested. These are all screenshots from the router's various configuration pages. I did take the liberty of removing private info like our IP address and other such data, so if you see a blank spot or a truncated number, it is me, not the router's UI.
This is the main screen you see when you go to the router's web interface. It has an overview of the network, link status and so forth.
Broadband Link Overview
A brief overview of the DSL link
Broadband Link Details
Much juicier information on the overall state of the DSL link. Note the true speed of the DSL link is 25 megabits. Only 18 is given over to data, which means the remaining 7 is for the TV and voice services. It would be great if AT&T offered the full 25 Mbit as an option in lieu of TV, but alas...
Broadband Link Errors
This page gives a list of all the various errors the DSL line may have experienced. From my research, the big warning signs of a bad connection are link retrains, errors and timeouts, as well as uncorrected blocks and severely errored seconds. Our screenshot has some scary numbers, but thankfully they were all from a service call 2 weeks ago while the AT&T guy was fiddling with our line. Since then it has been smooth (knocking on wood)
Private Network Summary
The main overview of the status of the private network, showing hosts and any active pinholes. You'll note two devices, *.65 and *.64; those are actually the two TV set-top boxes. They are just IP devices on the LAN.
The standard wireless settings page. It offers the usual security options. Out of the box, the unit has WPA turned on, which is good.
NAT Mapping Settings
This is the page where you set NAT mapping (pinholes) for games and such. The router comes with a huge list of predefined ports for mapping, and allows user-defined ports as well, both TCP and UDP individual ports or ranges. You can also place a device in the DMZ, although I have not yet tested this specifically.
Add a custom NAT mapping
The dialog to add a custom port mapping.
This is the router's overall firewall settings page. It offers basic protection from a variety of common attacks.
Private Network Address Allocator
This page allows you to set up address allocation for devices on the LAN. If offers both DHCP and static addresses, and you can also MAC address lock an address in the DHCP range to a specific device (so a device that uses DHCP will always get the same IP from the server)
This page allows you to set up some advanced features, including public routed subinterfaces and changing the IP range for the private network.
