AFP over TCP - Port Mapping on Time Capsule

So.. I want to be able to mount my Mac Mini from my PowerMac at work. I go to Airport Utility v5.3.1, select my TC on the left. Then I click the advanced tab, then Port Mapping Tab. I click plus to add a service. In the pull down menu, I choose Personal File Sharing. It fills in the port number 548 for Public and Private TCP. The private IP is filled in, but pointing to the wrong computer, so I adjust that..

Problem is.. when I choose a service, and the info gets filled in, there is an orange exclamation mark telling me that "A public TCP port number conflicts with a file sharing port number on the base station. Disable file sharing or choose a different port number".

I don't want to disable file sharing, because that's what I'm trying to get working!! I can't choose a different port number because that is the port used by Personal File Sharing..

Any insight is much appreciated?

1.83 gHz Mac Mini, Mac OS X (10.5.2)

just to update..

I have discovered that the message wasn't telling me to turn off File Sharing on the Computer, but to turn it off on the TC.. So.. now when I turn off File Sharing on the TC under the Disks Tab, it allows me to Map the Port.. which is cool.. But.. now, the TC is not sharing it's hard drive.. Which means, my Time Machine drive is no longer accessible.. rendering Time Machine, and The Capsule useless..

any ideas?

You need to map private TCP port 548 to some random public TCP port number. Any port will do as long as it's not port 548. Try port 1234. Then you'll need to specify port 1234 when you connect to your Mac mini.

I appreciate the reply.. But the warning message is showing that the issue is with the Public TCP Port, not the Private TCP Port... So if I change the Public TCP Port, how do I specify the port number when connecting the the "Connect to Server" option in the finder?

In "Connect To Sever" you would specify the public port by using a colon, like this...

afp://77.66.55.44:1234

Changing the port number, then using that port in the connect to server dialouge worked nicely! thank you!
