I'm trying to add a new server using one of my static IP address. I've added two previously with little issue but this time the changes don't appear to save. The device shows in Settings > LAN > NAT & Address Allocation. I see the list of “Public Fixed” address and pick the one I'd like to use. When I click save I'm asked to enter the password and I'm told in big friendly letters “Configuration Successful”. But the WAN IP Mapping still show “Router WAN IP address (default)”. No error message, no errors in the logs, it just doesn't save the change. Any Ideas ? Thanks Model: 2701HGV-C Hardware Version: 2701-100630-008 Firmware Version: 6.3.9.63-plus.tm
