I am are trying to configure GenieACS to manage an industrial 4G LTE router (Make - Proscend, Model - M360-P) remotely. The router is behind CGNAT and the public IP is assigned by the ISP dynamically. The router is able to reach the GenieACS server but ACS server is not able to reach the router.
I have tried using STUN/XMPP, but the router doesn’t support any of these configurations.
It will be of great help if someone can share with me any other alternate method to achieve remote management of CPEs behind CGNAT, where the CPEs don’t support STUN/XMPP.
