buffalonas.com will not work LS-WVLFD7 externally.
I am using 9000 locally and the NAS suggested 5 digit port externally in the NAS config. I have port forwarding configed in my router. I have tested this on canyouseeme.org. It is visible. I can access the NAS inside my network with no issues. I CAN access the NAS externally using my IP address and external port number. But when I try to use buffalonas.com, I get no response externally. It looks like the browser page is trying to load but never completes.
