Where I'm living, the walls are strong, therefore I decided to move the D-Link DWR-555 3G outside the house with wireless disabled and configured with 192.168.210.200, and brought a TP-Link TL-MR3420 inside the house with wireless enabled and configured as 192.168.150.10, connected them with Ethernet cable (from port 1 to wan port), and everything works great so far.
After, I installed the Iomega ix4-200d Cloud Edition on the inside router, and tried to setup a personal cloud. I registered with LenovoEMC. However the Storage Manager of the NAS keeps saying that router needs to be configured for port forwarding. So how could I do that ? And which router that needs to be configured ? Many thanks in advance.
