RV55 getting private IP address after setting up Dynamic DNS

AirLink Routers
1

We are located in the US, but we are using an SIM card provided by a South American wireless carrier with international roaming. We set up Dynamic DNS using IP Manager. The network status is “Network Ready”, but the modem always gets a private IP address like 10.xx.xx.xx. The modem is not reachable and not communicating. Please help.

Hi @tang.lei ,
Welcome you to our community
The failure of accessing the modem is caused by your private IP address, it seems not to relate to setting up Dynamic DNS using IP Manager.
Normally the network operator will provide you an private IP address if you use a normal SIM. So, if you want to access the modem by IP address, you have to contact your mobile service provider to get a public IP.

Thanks,

I agree with @jerdung , “The failure of accessing the modem is caused by your private IP address, it seems not to relate to” DNS. Forgive me, but is it possible that DNS is being confused for DHCP? Suggestions:

  • Check with mobile carrier for expected IP address assignment. Confirm you are not supposed to receive the 10.x.x.x (perhaps this is supposed to be a private mobile network?!).
  • Check with mobile carrier for APN settings.
  • Check with mobile carrier for expectations when roaming.

Thanks, @jerdung @henry.fordyce. We will contact the wireless carrier.
