No-IP updating to odd ip addresses

[MMTadmin]

So here is an odd one. I have DDNS setup on pfsense 2.4.2 using No-IP. Somehow it has updated to the ip address of my cell phone  :o and not the WiFi ip address but the actual Cell phone ip address. Any ideas how this happens?

You're not bridging your pfSense firewall to your cell phones hotspot are you?

[MMTadmin]

Nope

More information please.

Who is your ISP?

What method do you use to get your internet connection?

Generally around here cell phones are in a big NAT and get an address in private space..  my case my stuff gets 100.x.x.x

I am working with No-IP support now, but I think it's because I had the No-IP app on my Iphone that it updated the DNS. I have removed the app. I thought the app was just to monitor my ip address didn't know it would make updates. Waiting to see what support has to say.
