I'm unfamiliar with this issue but from readings on this list, but this
might be an ECN issue. search the archives for more info/explanation on
it. The quick answer is that you want to turn off ecn with a command
like this (as root):
echo 0 > /proc/sys/net/ipv4/tcp_ecn
If that works, make the change permanent by adding that line to
/etc/init.d/networking, like this:
case "$1" in
start)
doopt spoofprotect yes
doopt syncookies no
doopt ip_forward no
echo 0 > /proc/sys/net/ipv4/tcp_ecn
echo -n "Configuring network interfaces: "
ifup -a
echo "done."
;;
If the first command doesn't work in the first place, then I'm afraid I
can't help you further right now; you'll have to wait for someone more
knowledgeable to respond.
