ATT Fiber BGW320 - Has anyone truly been able to get IP Passthrough to work?
I bought the Deco routers to replace my aging Orbi routers which I had switched to being access points in the years past because they kept locking up.
My goal with this purchase was to use the Deco as my true router so I can have parental controls and change my DNS to an internal machine (PiHole) to block ads on the network.(The BGW320 does not allow custom DNS servers)
The problem I am facing is that the Deco router is not being given a true external IP address from the ATT Router, the "IP Passthrough" function does not appear to actually do anything.
On the BGW I have changed the following
1) disabled wifi
2) Turned off all firewall functions
3) Disabled packet filters
4) Enabled IP Passthrough
The Deco is still being served up a 192.168 IP address from the ATT router. Which is causing network slowness and the dreaded double NAT
Things that stand out
1) If you look online about this.... half of the posts say it's easy just set up IP passthrough. The other half say it's not possible.
2) I believe routers have 2 MAC addresses? The sticker on the bottom of the Deco state that the MAC address ends in "50" but in the BGW320 it sees it ending in "51". I've tried both. neither seem to work
Has anyone actually been able to get this to work? Or is it time to give up and return these Deco routers?

@SteveMat Try it! Look, I've have AT&T for many years, they never changed my IP Addres, not a sing time. The only time they did is when I moved to a new part of town and had to get a new set up. Even after that, I kept the same IP Address since.

@SteveMat I would definitely suggestion not to plug anything into the bgw, only the deco. Also I decided to run without ipv6 and noticed a lot of drops have stopped.

@kriihz I generally do not get any drops, just psuedo randomly when either Gateway reboots or the Deco, it gets a local IP Address and not the WAN address. As mentioned, I can reproduce the problem with either a Deco attached or my HP Laptop - so pretty sure this is a AT&T Gateway/Nokia issue and not a TP-Link issue.

@SteveMat It is ATT, I have two XE75 Pro and I have had some much issues, I finally went and put my DHCP into dynamic so it would stop kicking the mac,the connections from the gateway would drop randomly as well, I did a reset then I went in and reset all the connections again with the IPs and everything in the gateway, it's been a few days and have not seen a drop

@SGalbincea Seems to WAN Address seems to stick until the Gateway and/or Deco is rebooted. I can sometimes reboot the Deco once or twice and it will get the WAN address or if I change to PPPoE and back to Dynamic for Internet Connection, that always gets it to grab a WAN Address.

Thanks for this thread! I went through a number of advice here...
I run a Deco BE95 myself behind a BGW320-505.
I did all the things on the BGW320-505 to passthrough the public IP, not filter any data requests via the Firewall, etc.
On the Deco side, what ultimately worked for me was changing dynamic IP to a static one. Keeping all other variables the same, but changing the IP from the internal IP to my public IP that ATT assigned me.

@FiberKid Your default gateway and (probably) subnet mask may be off...

@jzchen so I've gone through this thread entirely and am trying to understand what I am getting into as I have a similar scenario. Please pardon my very simplistic understanding!
My setup is the same ATT BG gateway on a 1 gig fiber connection that I have had many issues getting/maintaining an Open NAT on my Xbox Series X or with manual port forwarding for the Xbox, remote Plex access from my desktop or remote play from XBplay through my Steam deck.
After countless hours configuring firewall settings and trying to make it work using ChatGPT's suggestions (which were quite good and helpful) with the default gateway, I've decided to pick up a Deco BE63 and attempt to use the IP Passthrough feature.
My understanding of the issue everyone is having is that the IP assigned to the Deco doesn't stay the same and that causes drops/speed loss? It won't just work as simply as plug in, set IP Pass, turn off gateway firewall and Wi-Fi and that's it?

@Snar That's a good question. My initial thoughts while I was reading your post to the purchase of a BE63 was don't...
The issue that is happening (what is being discussed in this thread) is that IP Passthrough seems to fail to Passthrough a WAN address to the TP-Link router. (I've experienced this with an ASUS router as well). When it fails then your BE63 would be assigned a LAN address, and you'd then be in a worse situation of what's called double NAT. It is the opposite direction of what you are trying to do with the Xbox.
Once the IP Passthrough is achieved, it seems to stay active unless some kind of reboot is done on the RG or the router (BE63 in your case) then a LAN IP may be assigned again, back to double NAT.
It is possible you'd have better luck with a BE63 connected, I'm really not sure. My Xbox 360 and PlayStation 3 are directly connected to the BGW320 for full disclosure....
