OS? Two things immediately spring to mind with Linux 2.4.x - ECN and MTU
path discovery, both settable in /proc/sys/net/ipv4 - ip_no_pmtu_disc
and tcp_ecn. With RH 7.x for example, both can be set in rc.local.
ip_no_pmtu_disc should be 1, tcp_ecn should be 0. They don't do much
good, anyway, in practice.
Of course, I could be wildly wrong :-)
