IP Passthrough issue
I'm using ATT fiber and have set IP Passthrough on. It worked fine correctly in the past and I was able to ping my external IP/tplink ddns but there are times when it loses connection. Like the past few days, I can't ping my external IP. I can't ping the DDNS i set on the Deco app. I have tried resetting the ATT modem and router but that didn't resolve the issue.
Anyone else had this issue? What have you done to fix it?
Thanks!

@peekeesh Did you verify the IP passed through, and the DECO is receiving the WAN IP vs private IP?
If not reboot the AT&T gateway, pause 20 - 30 seconds, then power cycle the DECO. Hopefully with a little timing as such it does correctly pass through the WAN IP...

@peekeesh I'm afraid there's a bug, either with the gateway or the Deco. I had the exact same issue with an ASUS router, where I had to time the power cycling of both just right, otherwise it got a private LAN IP from the gateway. I noticed at one point the BGW320-500 got new software, and now if I reboot the ASUS router it would get the WAN IP Passthrough...
I somewhat recently switched my BE95 as router for IP Passthrough, and same thing I needed to power cycle both otherwise I got a private LAN IP.
If there's a new firmware released I would not hesitate to download it. I believe there's a way to revert back no? (Never tried to revert to be completely honest)...
