The easiest way to get this going (assuming you have routers separating network segments, or assuming no one outside your network can access the web):
IF you are referring to "Web Access" (the file explorer interface) do the following to get this setup easily (you can change settings later as you see fit):
Step 1: Configure your router to Forward port 9000 to your Linkstation on port 9000.
Step 2: Configure your Linkstation Web Access settings to have external port 9000.
Step 3: Configure your name + key in Web Access settings and use buffalonas.com option.
Assuming Step 1 was successful (some routers may need to be rebooted etc for settings to actually start working) and you configured things properly in steps 2 and 3, you should be in business.
Typically people have problems w/ validating that Step 1 was successful, but it's a Router-level issue.
Let us know if this works.
