Deco M9 and AT&T Modem Passthrough Issues
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
Hi, I'm trying to get my Deco M9 to work in IP Passthrough mode with my AT&T BGW320-505 router for port forwarding. Following a process I've seen recommended for this modem that instructs setting up the modem as in the screenshot below, I am having not having the same luck. Has anyone had luck getting this to work with this mesh/modem combo?
One possible issue is that the MAC address seen in the modem's client list (populated in the highlighted field below) is different from what's in the Deco app. I've seen that Decos can have multiple MAC addresses based on their connection method (LAN/2.4/5 GHz), and that one user had success by finding and trying the different MACs. Could anyone tell me how to find the different MAC addresses to try? Thanks in advance.
@David-TP thanks for your help. The main Deco (which is the only device connected to the modem) shows up in the "Choose from" list. That screenshot is below. The MAC address listed (ending in :20) is the one on the Deco+1 in hexadecimal (MAC printed on the product ends with :1F). I have tried both of these MACs, but none worked. Anything else I can try?
