| This is just another former DTV tech posting his 10 cents on this subject. I am pretty sure without totally erasing and rebuilding the firmware/Software from nothing. You are wasting your time. I will give you a little hints. The X2 has 2 images of the firmware in the modem. Make sure you get them both erased otherwise the modem is programed to copy the second back to the first after it is erased.

You missed the point. I'm not reprogramming new firmware into the modem. I'm creating a replica of DTV configuration server for ISP to run, so unaltered modems can pick up configuration.
If you can contribute more precise protocol description for HTTP-based config protocol, or a dump of HTTP traffic session from modem to gateway, it would be appreciated  |

Another thing to consider is if the modem side can be set to bridge mode without re-flashing the firmware. Currently the gateway gets one IP on the WAN side, then a .252 on the LAN side. In my case both sets are routable. I think they are/were the only ISP to do this.

Forest Hills, NY | Most likely its not able to do pure bridging. As I previously said, ISP's cooperation will be necessary to get these modems working with any ISP... |

No, anyone selling RFC1483 routed service can do it this way. I have a .248 LAN behind a single WAN IP on my EF 5660 in RFC1483R mode.
What was a bit different with DTV is that they do this on RFC1483 bridged service, not routed service. That is to say, you can yank out their gateway, replace it with a bridge, and the result can be used to recover and use all four of the /30 IPs as well as the LAN IP if it's public.

Forest Hills, NY | Correct, you can use a standard modem with DTV service, but you can't use DTV's modem with any ISP that doesn't do routing DTV's way (/30 for "point-to-point" and /30 for LAN)... |

| It's /24 for WAN and /30 for LAN.
You may want to look thru the recent posts here. There was an ISP who, as part of their pitch to transition DTV customers, claimed they could re-use the DTV modems. However, they could not pull this off in the end, but supposedly managed to get inside them to some degree before deciding they were unsuitable.
Perhaps they will share notes with you. |

I am an engineer with Florida Digital Network trying to find a way for our ADSL customer's who have recently switched to us from DTV to use their existing modems. I would be willing to help in any way I can if it is of assistance. Let me know if I can do anything.
