[Xitami] Problems setting up xitami behind Roadrunner ISP

[Control-Freak]

Hello,

This is my first post to the Xitami list.

I am having a problem configuring Xitami to work behind the Roadrunner ISP.
I can get FTP to work on port 21 if I leave Xitami at its defaults, but
since Roadrunner blocks incoming port 80, I had to adust the portbase to
55000 to use port 55080 with allows HTTP to work.  The problem is that I
cannot get FTP to work at port 55021.

So, I tried adjusting the FTP port varible to -54979 to get FTP port 21
again.  But this does allow FTP to work either.  I also tried adjusting the
data-port variable to -54800 to get the data port back down to 200.  This
also does not work.

Is portbase adjusting something else that needs to be readjusted for FTP to
work?  Does anyone have any ideas?  I really need both FTP and HTTP.

Thanks in advance for your help,

Jay Aldrich
