| AT&T Uverse 3800HGV-B gateway but different ISP Issue...
Ok, I will try to detail this as best as I can. I basically have two networks internally, since the install of the AT&T UVerse Phone / TV Service (ONLY - NO INTERNET FROM AT&T).
I have attached a link to a PDF file describing my network configuration. I have changed the external IP address for security purposes.
What I am trying to accomplish is to get the AT&T Uverse network (which does not have direct internet - BOTTOM OF THE DIAGRAM) to be able to browse / search for machines in the home network (TOP PORTION OF DIAGRAM). The Uverse offers MediaShare and I would like to be able to have the MediaShare application be able to find the laptop machines on the home network, so I can seemlessly be able to open up shared media items from any machine on the home network. I have no problem modifying the home network addressing scheme. I tried making it part of the same subnet as the TV's but I was not sure about how it would function if I disabled the DHCP server on the network. Can anyone help me out here. Please be as specific as possible if you don't mind.
Thank you in advance for you help.

| Change the subnet on the U-Verse to match your other LAN, restart the STBs. Disable DHCP on your LAN and assign everything a static IP address. Connect both networks with an Ethernet cable.
If you want to get adventurous you can disable DHCP on the RG, and configure your DHCP server to assign the STBs the correct default gateway and DNS. -- PRescott7-2097 |

@rr.com | How would I go about setting things up to have my home network provide IP's for the at&t net. Simply plug in a cable and disable dhcp on the AT&T side that will allow all of the equipment on the AT&T side to grab a 10.0.0.x address..? |

@rr.com | There is a Netscreen 5XP in there can we not configure one of the ports on there to handle the routing between the two subnets..?
Just a thought. |

@rr.com | reply to joako Correction make that a Netscreen 5GT with current support. |

| There's another thread about it. You would need to run some sort of IGMP proxy, I haven't tested it myself and couldn't tell you if it work work or not. What I post above certainly would.
Maybe you can contact Netscreen's support and ask them? Tell them you have 3 MAC addresses that you want served by the DHCP server but want those machines assigned a different default gateway and DNS? I don't have any experience with Netscreen so I couldn't tell you.
Worst case setup a box to run DNSMasq, ISC-DHCPd, etc. Even then I've never attempted the configuration I specify but I don't see why it wouldn't work. I know DNSMasq can send different options to the host based on class, vendor, MAC address, etc. -- PRescott7-2097 |

| reply to CodingPilot It looks like your Netscreen is running pretty much default settings which if that's the case it will act as a DHCP server but only if it does not see there are other DHCP servers on the network. Your exchange server is the DHCP server? So you'll want to physically join the two networks, change the internal IP of the AT&T router to have a static in your 10.x.x.x/8 and disable any DHCP that may be running on the AT&T router. Once all devices are in the same subnet they should discover each other easily. Be sure the subnet mask is correct on all devices. |
