Monitoring end point and CPE using PRTG

Hallo Baicell community,

I have 2 APN, 1 for my end point (PC) and 1 for my CPE. We use local server.

Can we make ip address CPE and PC pingable from PRTG Server?
Currently only IP end point (PC) that reachable frok my PRTG Server.

Thank you for your response

Just verifying you can ping the device behind the CPE but not the CPE correct?
