My internet comes in via the Verizon router I then connect the Deco to the internal port of the router (same way that I had the C90 router). All work fine if I leave the WAN side of the Deco set to Dynamic wich gets an IP from the Verizon router internal DHCP, but when I try to set it to to a static IP within the Verizon router internal network and out of the verizon DHCP range I get a red message stating "invalid IP address" even when I used the same Subnet mask and gateway info that the Deco gets from the Vz router when in Dynamic setting, the only thing that changed are the last 3 digits from the IP address.

Any help would be welcomed, as I need to set the WAN to static because of port fowarding from the VZ router to the Deco (same that I had in my C90 router).

Thank you.
