3600HGV - Need to Disable DHCP

The 3600HGV is a derivative of the 3800HGV-B, which is used for U-Verse installations that have TV service.  The TV boxes require DHCP from the 2Wire, so there is no option to turn off DHCP on the 3800HGV-B.  This behavior was carried over to the 3600HGV even though there are no TV boxes.

To use your own DHCP server, you will need to install your own router in between the 2Wire and your network, and turn on the DMZPlus feature of the 2Wire.  This will give your outside IP address to the WAN interface of your own router.

THANKS!!!  I REALLY APPRECIATE the quick response!!!

 

I'm new to the U-Verse plan and can see the need for other connected devices to get DHCP that way.  Our setup is only using Internet.

 

I'll check to see where to turn on the DMZPlus feature.  I don't remember seeing it but wasn't looking for it either!  I'll also pickup a new router! 

 

Is there any speciffic brand/model you would recommend for this setup or is basically any router going to be ok?

 

Is there a link available to download a user guide for the 3600HGV ?  All I've been able to find is the installation guide.

 

Thanks again!

THANKS!!!

That took care of the DHCP issue!!!

• Since you have your own DHCP server, you'll now need to go to the web configuration of your router and turn off it's DHCP.

WHICH ROUTER DO I turn off the att or mine for the dhcp.

You can't turn off DHCP on the AT&T router (the 2Wire).

You can turn off DHCP on your own router that is set up as the DMZplus device.  Whether you would want to turn off DHCP on your own router depends on what your IP addressing solution is.

The original poster had his own server that functioned as a DHCP server on his network, thus he needed to turn off DHCP on his own router after it was hooked up, because you cannot have two DHCP servers on the same network.

If you do not have your own DHCP server but you want your client computers to use DHCP to configure their IP addressing, then on your router you should leave DHCP turned on.

OK I think I found the correct thread. I think my intent is the same. Please verify that I correctly understand.

Currently I have At&t DSL with a Dlink DIR-655 router it is the DHCP server and has one IP address reserved for my print server.It also handels the WiFi.

I ordered U-Verse internet only and they will be sending the 3600HGV I told them what I wanted to do and requested a MODEM only but are sending the 3600HGV.

So that being said I want to still use my router and it's WiFi and not the routing function and WiFi of the 3600.

According to this thread I should do the following."

• Pick an IP addressing range for the LAN side of your router that is different from the IP addressing range that the 2Wire 3600HGV uses.  By default, the 2Wire uses 192.168.1.0/24.  You can pick something like 192.168.2.0/24.
• Use an Ethernet cable to plug one of the LAN ports of the 2Wire into the WAN port of your router.
• Plug your computers into the LAN ports of your router.
• Go to the web configuration of the 2Wire at 192.168.1.254, and turn on DMZPlus for your router (your router will appear as one of the devices in the 2Wire's device list).
• Once DMZPlus is turned on, reboot your router, it will get the 2Wire's outside IP address on its WAN port when it comes back up.
• You should now be able to connect to the internet."

So this means that I will have to disable the DHCP feature of my DIR-655 correct?

I have one reserved DHCP IP address for the print server this will now go away if I disable DHCP on my DIR-655 correct?

The DIR-655 IP address are 192.168.0.xxx so I will not have to change these correct?

Will I be able to add a DHCP IP address reservation for the print server as I did on the DIR-655?

What do I do with the routers previous authentication settings that I had with the previously bridged DSL modem?

Is there a MODEM only option (2210) for the U-Verse internet only folks like me?

I really appreciate it if you can clarify this all for me.

Thanks, Bob

If you have already set up your DIR-655 like this under ADSL, you can basically keep all settings the same on your DIR-655.  You'll keep DHCP on, keep your DHCP reservation, keep your IP addressing subnet, and keep your authentication information all the same.

You can set up the 3600HGV for router-behind-router using this post.

The 3600HGV is the only router for internet-only VDSL installations.  The Motorola 2210 is not VDSL, it is ADSL2+.

As far as port blocks, inbound 8000-8015 is blocked, but 22 is not.  This was confirmed by another user after I had already posted that.

Yes, you can leave everything on your DIR-655 the same except for the WAN authentication information.  The U-Verse RG takes care of all authentication.  Your DIR-655 is probably set up for PPPoE.  You will need to disable that and change the WAN connection method to DHCP.  Your DIR-655 will get the WAN IP address via DHCP from the U-Verse RG.  Following my instructions in the link above will make the RG hand your DIR-655 the outside public IP address, which is equivalent to what you have now with ADSL.
