Q: How to use Airport Extreme with ethernet leased line
Hello friends,
Just wondering if Airport Extreme is a real router, can I connect the ethernet drop of my leased line directly into it's WAN port, instead of putting the ISP provided router in between ? I have been through numerous posts and all seem to suggest connecting a cable/dsl modem to the WAN port of the Extreme. Didn't find any info where it shows the ethernet leased line connecting directly into the Giga WAN port, without any 2nd device in between.
If it can be done, then I also presume that the ISP provided public IP can be put in the WAN interface of AE. Can anybody elaborate more on this and detail out the configuration steps ? Since the AE has basic NAT firewall I think it can be done, but can anyone confirm please.
Thank you so much.

You will need to use a router mode of DHCP and NAT on the AirPort router for this type of setup, as I originally suggested with a note that this may create a Double NAT error depending on how your provider has set things up.
Go ahead and use the DHCP and NAT setup, and if you see a Double NAT message, you can test to see how the network behaves with the Double NAT. If you don't see a Double NAT and the network allows you to do what you want, then all is well.
