Airtel Xstream Zyxel PMG5617-R20B ONT Port Forwarding

That's unfortunate. I only got the router switched, I could forward ports on the previous router easily. I'll see if I can get the technician to give me another router of the older model


I'm forwarding ports 8096 and 3389 for my media server and remote desktop respectively, and I was forwarding ports successfully even with dynamic IP with my previous router, I'm not sure how the change of router caused me to go from dynamic public IP to CGNAT, but I'll try to contact them
I've been reading such responses that help users one way or another. Is there a resource for understanding the essentials of home networking and troubleshooting, that specifically addresses the issue of port forwarding, mac binding, etc.?

Airtel doesn't respond to queries that ask for control of routers.
