telnet ok, HTTP not

Hi again.

I'm getting this strange behavior and can't see where I'm wrong.

I'm redirecting all traffic hitting my firewall @ port 55555 to local 
port 80, in order to bypass some ISP limitations.

Now, when I try to view my start page from another machine (lynx 
123.123.123.123:55555), I get a fast 404 not found error from 
publicfile.

Right after that, and from the same machine, I do a telnet 
123.123.123.123 55555, get instantly connected, and with a GET I can 
see my page! (or any page in the site, for that matter)

Any ideas? In case it helps, the ftp server works fine.

Thanks
