AirPort Extremet - Double Nat problem

[HeroBiX]

I got status: "Double Nat" on my Airport Extreme, version 7.6.3

My modem is a SMC Networks
Model Name: SMCD3GN-RES
Software Version: 3.1.6.42.5S

I tried to disable the NAT on the "SMC Network", but that makes internet die.

How can I fix the double NAT problem?

Why do you want an Airport Extreme and the SMC SMCD3GN-RES ?
You can also run the AE in Bridge mode and that will then use the AE just as a WiFi Access Point. Are your LAN devices connected to the AE or to the SMC ?

You need to disable all the Commercial Gateway Functions and just use the SMC as a modem (if that's what you want).

It's the SMC who is connected to the internet, it has a special cable, look like an old TV-cable, back in the days.

At the moment, everything is connected to the AE ->then-> SMC ->then-> THE Internet

Thanks a lot, I will try the link when I get home

Disable the warning...if everything works the way you want, double-NATting isn't an issue. I have my cable modem connected to my AE which feeds two other routers on my home network - configured as two subnets because I do computer repair work and I don't want virus-infected client machines leeching bad stuff onto my "home" network - so I keep the two subnets isolated. Anyway - the AE has NAT turned on as do the other two routers....the AE complained about it, but it doesn't stop anything from working properly.
