4G Modems with private ISP IP number

Karlinco — Fri, 25 Oct 2019 04:52:26 GMT

Looking to set up Arlo in Uruguay. House has a 4G LTE USB modem plugged into a TP-Link WiFi router. Antel, the national ISP, does not assign public IP numbers to these Modems but rather private IP numbers. So I can't reach any devices at the house remotely and services like ddns will not work. Can Arlo work in this scenario?

One important aspect is that Arlo subscriptions aren't available in Uraguay.

It sounds like they are using carrier-grade NAT. That is becoming more common as ipv4 addresses are depleted.

Arlo should work with that, although I haven't tried it myself. I do double-route though - which has the same topology - and Arlo does work for me. However, ddns does work with my setup (since my edge router isn't shared).

I believe Arlo is designed so that the base station always initiates the base->cloud connection - which works with all NAT setups.
