Airport Extreme N Port Mapping?

[geofferyj]

Just got my Aiport Extreme N and I'm having serious issues with setting this up.

Here's what I want:

MacBook Pro to access iMac 24" at home when I'm on the road. I've setup Share Disk Over Wan, but all that does allow for me to access drives plugged into the Airport itself. Not my actual iMac HD.

I've tried to open ports up by using the Airport Utility and I can't seem to get this to work. The File Sharing Service will not allow me to "continue" when entering the ip info. I get a yellow error with no message.

What's wierd is I can use Remote Desktop perfectly. If I could just get the file sharing to work.

Anyone?

The way I understood it, the Extreme uses 548 to share the USB drives plugged into it.

I read something about port forwarding 549 externally to 548 internally (on your iMac), but I've never tried to connect externally, so I'm not sure how you'd tell your MacBook Pro to use 549 vs. the default 548.
