5031nv: how to change device IP assignment from static to dynamic/DHCP?

I have a router that's connected to 5031nv.  The 5031nv is assigning it a static IP.  How do I change it so that 5031nv assigns it an IP dynamically (via DHCP)?

 

This is what I see when I log into 5031nv:

@Pete7874    Have to put the router in DMZ zone like these Computer Joe 2wire/Pace/Arris Instructions:

 

This is what I did to use an "internal" router. I set my "internal" router to use DHCP for the WAN address, plugged it's WAN port in to the RG, reboot the "internal" router, let the RG assign a local address to the "internal" router and then set that address to the DMZ in the RG's management interface. When I go to the "internal" router's management interface it shows as having the same WAN, gateway, and DNS addresses that the RG uses.


I set the "internal" router to assign addresses to "my" side of the network in a different IP range than what the RG uses (192.168.2.* instead of 192.168.1.*) but using the same subnet mask (255.255.255.0). My internet works fine with no interuptions and local network tasks (back ups, streaming, etc.) work as expected.


I can also still access the RG from "my" side of the network when I need to without having to change any network settings or swap any cables. Leave DHCP running on the RG. You do not need to disable the firewall in the RG as the DMZ will open a pinhole through it to the address you pick (your internal router). If you have existing wireless on your router that your satisfied with and want to keep, just make sure to turn off the wireless in the RG.


As for the STBs they should be run straight out of the RG with CAT5 or RG6 Coax.

 

Good luck 😉

The 5031nv is not letting me add my internal router to the DMZ because it thinks the router has a static ip assigned.  and i cant figure out a way to change it from static to dynamic.

That would be something you would change on your Router.  Apparently it's configured with a static address and is reporting that IP address on the LAN and the 5031NV hears it and records it.  If you change your router to ask for an address on the WAN side, then it should show up as Dynamic (DHCP).

 

However, I would not think that having a static address assignment would stop you from assigning it to the DMZplus zone.

I already have my router configured to ask for an address on WAN side.  5031nv still thinks it has a static IP.

 

When I try to enable DMZplus on it, 5031nv gives me this error message:

 

The selected device has a static IP address. DMZplus requires that the selected device use DHCP to obtain its IP address.

I think I'm going to have to do a factory reset on the 5031nv, hoping it'll forget about my router, and I can then start from scratch.

 

I just hope it doesn't wipe out my DSL/U-verse connection settings, so that I can still get back online.
