The Web Access service on the Linkstation runs on TCP port 9000 (this is on the LOCAL network). That port cannot be changed.
The External Port number (in the Web Access-> Service Setup section) is given to BuffaloNAS.com, along with the public IP address assigned to you by your ISP. BuffaloNAS.com does not channel your files, it merely redirects your browser to
http://xx.xx.xx.xx:port/
, (that's supposed to be a colon next to the letter p)where "xx.xx.xx.xx" is your public IP address, and "port" is the External Port number. After the redirect happens, your browser is communicating directly with the Linkstation's Web Access service.
If you use External Port: 9000, the port forwarding you have to do is much easier. You can just forward port 9000 to the Linkstation's local IP address, with no mucking around with Public (WAN) ports or Private LAN ports. The connection looks like this:
Your remote computer --> TCP port 9000 --> Router's public IP address --> TCP port 9000 --> Linkstation's private IP address
If you set External Port to anything other than 9000, you'll need to do more specialized port forwarding, and your router needs to support it. In your case, forward Public (WAN) port 9009 to Private (LAN) port 9000, and the connection looks like this:
Your remote computer --> TCP port (External Port) --> Router's public IP address --> TCP port 9000 --> Linkstation's private IP address
