YOu can do the same port forwarding with Starhub 10GB. I am doing it now without any issues.
Thanks for your input
I had got port forwarding info from other credible local source.
Called up 1630 (sales) and route to their technical dept (not-1633) for double confirmation.
Other smaller telco also had addon for static ip for port forwarding.
Simba fibre 10Gbps, yes very cheap, but this CGNAT required too much efforts to achieve port-forwarding, via tools/utilities, for IoT, the best option is OpenWRT in compatible router with WireGuard plugins.
By early August I will be on Ultraspeed 10Gbps, now looking for cheap offers on second router in Carousell for ethernet backhaul Easymesh.
I had already placed taobao orders for aircool 10G switch, SFP+ multiple-mode modules, and LC-LC cables and connectors and faceplates. Future-proof network infra for room-to-room.
