I have it set up with the WiFi connected to a T-Mobile Home Internet gateway at 192.168.12.1 (This address cannot be changed.)
The AC1450 is at 192.168.12.2 I have dd-wrt configured to repeat the WiFi from the T-Mobile gateway and bridge/route to its ethernet ports, a second WiFi AP, and a virtual interface dd-wrt_vap
The issue is nothing downstream of the AC1450 on any of its WiFi or ethernet interfaces gets IP addresses assigned by the T-Mobile gateway.
How do I fix it so client DHCP requests go through the AC1450 to the T-Mobile and responses make it through to the clients?
All my stuff is in the 192.168.12.xxx range so any device can easily access any other device, including a media server with DLNA.

I think what you are looking for is setting up as a `repeater/station bridge`
Note that using an ethernet cable between ISP router and DDWRT route is the much better solution
If you still want to connect wirelessly use one of the radios as station bridge and then you can use the other to distribute local wifi,
The Netgear AC1450 is in my shop. To connect it to the T-Mobile gateway in the house would require 60+ feet of cable and going through three walls, one of them concrete block.
Using the wireless link to the gateway is physically the easiest way.

I assume that '102' is a typo.

Based on your Subject, the issue is you're trying to use DHCP Forwarding, which is for DHCP from another subnet.

Follow egc's links for Client (/Station) Bridge to connect your AC1450 2.4GHz to the T-Mobile Gateway and then rebroadcast on the 5GHz radio. Unless the AC1450 gets good 5GHz signal from the gateway.
A note for Broadcom devices (which is probably already in some of those wikis): bridge modes can have issues with more than a couple clients. If so, use Client (Station) Mode (not ...Bridge) instead. Another note: as I recall, if a WAP/CB(/SB)/RB isn't getting time (NTP), you need to set the Gateway (to 192.168.12.1 in your case). _________________ #NAT/SFE/CTF: limited speed w/ DD#Repeater issues#DD-WRT info: FAQ, Builds, Types, Modes, Changes, Demo#

What I need is what in dd-wrt does what installing and configuring relayd does in OpenWRT?
I need everything in the same subnet with the T-Mobile gateway being the only DHCP server for any device not manually configured with a fixed IP. Those would be phones, tablets, computers I'm working on or otherwise have temporarily connected by wired or wireless.
I want to have a media server running DLNA plugged into the T-Mobile gateway, accessible from everywhere in my local network. Since DLNA isn't routable between different subnets like regular Internet traffic, that's the way I need and want my network setup.
With older dd-wrt versions on this Netgear AC1450 I had DHCP passing through it, but upon hitting save and apply the router would reboot and be "invisible", acting like a dumb switch but with its wireless link to the gateway acting like a virtual Ethernet cable *and* also a repeater of the gateway's SSID *and* its own AP. Despite being required to assign the Netgear router an IP during setup, nothing was accessible using that address after saving the setup and rebooting.
But any time I needed to get into it to change any setting or update dd-wrt it had to be reset and reconfigured from scratch because it wasn't possible to save the configuration to a file.

well, I have to bump in... DHCP Forwarding can be done on Netwotking.asp:
but it is some kind of BS kernel hack because broadcom driver lacks multicast support... and multicast is needed for relaying dhcp... and there are some other things but lets not complicate it for you... just forget dhcp forwarding....
