Perhaps the cause could be found in this thread... https://community.globe.com.ph/message/105661#105661
When Globe implemented the Carrier Grade NAT (Network Address Translator), it is causing the IPv4 to be starved or exhausted by assigning many customers to one IP address, as opposed to giving each customer their own IP address.
Opening a port on your home router will not help, because the upstream Globe NAT gateways break end-to-end connectivity.
From the subscribers point of view... tinitipid na tayo ng Globe when they could have invested and put out a better infrastructure (iPv6) or they would want us to subscribe an additional service like having a Static IP address.
got the same prob.. changing to aztech router would it solve the prob?
