In the rl0 branch there is a linux server connected and I experienced about 2kbs transfer rate each other. So I wrote a message asking on more help . Here it is the link: http://www.freebsd.org/cgi/getmsg.cgi?fetch=315034+322751+/usr/local/www/db/text/2000/freebsd-questions/20000709.freebsd-questions Btw now the problem is solved changing the HUB at 10mb with an HUB at 100mb and we succeded in reaching almost the full 100mb speed in ftp this box from the other ones. I think rl* driver is very sensitive (and faulty) to combinations of 100mb / 10mb network. Please let me know...
