Thanks Ben, Would the tulip driver patch for 2.4.19 found on your website work with 2.4.29? The only reject I got is from interrupt.c. It looks like the reject is due to a misalignement on the first line of that patch. Also do you know of any way to test MTU problems. Should I just use ping with a large payload? Do you know of any way to force a Windows client to adjust its MTU automatically (apart from tweaking the registry), for example an option in DHCP?
