Port Forwarding Modem/Router and Google Home WIFI.

[SunBroJonik]

I have a google home system and i want to allow ports 7000-7500 on my local System. I have a Ethernet to my google home wifi which is connected to our modem router system. I attempted to port forward the google home Lan address(192.168.86.1) not WAN (i allowed ports 7000-7500 in that port forward). I then went to the google home system and allowed my system Lan address (192.168.x.x) with the associated ports. I would assume i made a direct tunnel for these ports to go from the Modem router -> google -> my system but when checking the ports it does not seem like it has worked. How do I port forward/what am i doing wrong

Hey @SunBroJonik .

Is the "modem router" you note being used as just a modem or is it being used as a modem and router?

[SunBroJonik]

It's being used as a modem and router. Our isp set it up and roommate didn't care for my Google system, I needed a Lan connection to my pc

Thanks for the additional info, @SunBroJonik .

The port forwarding isn't working because you have two devices trying to route the same traffic and creating a Double NAT situation. The only way to run a separate network is with either a modem only device and two routers using separate connections to the modem or have two separate services coming into the home; the former will cause bandwidth issues and the latter will be more expensive.

Fix Double NAT when two routers run at the same time

Thank you! Saw someone have a similar issue but didn't know if it was just a WAN thing. Thought I could avoid disabling the router if I just forwarded the LAN ports.

I tried using Bridge the connections. Didnt work. tried PPoE on the google home, broke everything. Bought some Eero pros.
