Networking Trouble (firewall?)

Hi everybody,

I'm having some trouble with connectivity after installing Brickhouse.
When trying to connect to any ftp server with Fetch, I get an "Error:
There is no host by that name" message. Strangely, I can connect to
ftp servers via the command-line ftp client "ftp". I'm also having
similar trouble with Unison -- but I haven't figured out how to use a
usenet client from the command-line. The world-wide-web works fine in
Safari and on the command-line.

So, I'm really just confused. I think Brickhouse might be causing some
trouble, but then I can't see why command-line clients should work at
all either. And I can't really think of anything that would cause
networking trouble *just* for *some* GUI programs.

Any ideas?
'cid 'ooh

PS - Is there an easy way to revert the ipfw configuration files back
to stock? I want to get rid of Brickhouse.
