Wrong Server IP Displayed in Login Box

When I try to log in to iFolder (3.8) from the outside using our external address, I seem to be able to reach the server OK. But the address which is displayed, which points to the internal address of our iFolder server, is incorrect. I suspect that's why I keep getting the "invalid credentials- please login again" error.

I can login just fine inside our building using http://(internal IP address)/ifolder and http://(internal IP address)/admin.

I am at a loss as to where that address is stored and how to reconfigure it. I can't find the address listed using the iFolder admin pages. I used Yast to check the iFolder setup in OES 10. All seemed good. I ran the simias-server setup utlilty. All ran well.

I am obviously missing something, but I don't know where to look. Any ideas?
