Hi,
I've been having weird problems with 2.4 kernels ip networking. I can't connect
to several sites ( hotmail.com,intel.com... ). After some investigation with
tcpdump I figured that the IDentification field of every outgoing ip packet is
set to zero and then it doesn't get through some few firewalls. I'm surprised
I haven't found anything about it in the list archives, so I'm trying to get
help here. Did I forget to configure something?

No, the sites have firewalls erroneously blocking ECN, try:
echo "0" >/proc/sys/net/ipv4/tcp_ecn

Did you configure IP: TCP Explicit Congestion Notification support? If
so, this breaks some older firewalls, which probably won't be updated any
time soon.
