I have just been obliged to change my setup to a different internet provider. FMS 16 running on OS 10.13.3. I am not an expert on configuring internet service setups, but having been trying to reproduce what existed on my previous provider. I am now in the strange position where Filemaker client and Webdirect work correctly from computers outside my local network via a DNS address. On the local network Filemaker client only works via the local address on FMS. The DNS address fails to connect. As for Webdirect it also fails to connect on the local network. I can't get my head around what could be impeding the connection locally but not from outside the network. Here's a little summary of what i have tried to implement to get this up and running. I realise that some of the things I have done are superfluous. But as i said I am no expert.
I have
reserved my DNS address as a "IP address reservation" using the MAC address of the computer on which FMS resides.
designated my DNS address as the "Dynamic DNS"
turned NAT on
used Port Mapping to open TCP and UDP ports including ports 16000, 16001, 5003, 80, 81, 443, 389
designated the local IP of the compute on which FMS resides as "DMZ"
turned the firewall off.
designated TCP and UDP ports including ports 16000, 16001, 16020, 16020, 5003, 389 as "special application"
So would anyone have an idea what I need to do to make Webdirect and Filemaker client work on the local network using my DNS address? And possibly let me know what of the above is superfluous.
