I am on double NAT (behind 2 routers).
I known how to get the public IP by visiting some webpages or use dig command.
Yes I known WAN IP usually same as the public IP.
I talk about WAN IP #2 that can be a private IP.
I tried tracert and pathping commands but didn't work.
Maybe we can't known the WAN IP by general way.
But I saw one IP camera app can find it. Maybe it's "tinyCam Monitor" on android.

Hi @Boontawee Home. the question would benefit from additional clarifications. For example, you saidI known how to get the public IP by visiting some webpageswhat do you mean by that? What commands did you try? Additional clarifications may help us to analyze your problem more accuratly!

I think you'd need some client on that address space... or a STUN service running on the "internal" WAN

Do you know any details about the first NAT router? Also,tracertandpathpingare Windows commands. Is there a Linux host on LAN with private range 2? AFAIK,tracertuses UDP packets; you may trytcptraceroutefor TCP packets ormtrfor ICMP packets, in the case the NAT router treats them differently. Some routers also offer an UPnP interface to sidestap NATing; you could try that as well.

There is no general way to find out the address WAN IP2. Why would you need that address?

Private LAN clients can known external IP only when the router enabled uPnP
I had recheck the android app "tinyCam Monitor". She known the external IP when router is enabled uPnP feature.
So I check around internet and found MiniUPnP (http://miniupnp.free.fr/) command that can show the external IP via UPnP/IGD. I don't know much about UPnP/IGD.
Old routers notes
UPnP implementations are potentially subject to security breaches. Badly implemented or configured UPnP IGDs are vulnerable. Security researcher HD Moore did a good work to reveal vulnerabilities in existing implementations : Security Flaws in Universal Plug and Play (PDF). A common problem is to let SSDP or HTTP/SOAP ports open to the internet : they should be only reachable from the LAN.

To make this a useful answer, at least describe how you used MiniUPnP, what your particular router showed when using it, and what brand and model of router it is - things will likely work differently for other routers.
