So I started playing with WD. It is an interesting environment.
It works only on the local network. There is a problem with using port 80 as it is already used and it would be great if I could change the port, but it seems that may not be possible. I have read a number of threads about this.
Port 5003 is open and FMP /Go clients have no problems.
So I figured I would just have peopel access through port 443, but that is not working either and I cannot tell why. I am not sure if I need an SSL cert specifically for this. I do not get a warning, just page not found.
The best thing for me would be to change the web direct port in Filemaker.
Figured this out. Got port 443 working.
I also made the mistake of trying to test the connection from a machine inside the local network. The router doesnt allow local machines to browse local content via the WAN and then back into the LAN.
