I discovered a difference between the 2.1.7 and 2.2 tcp/ip stack that I cannot explain. If I have a host in a subnetted C-net, say 192.1.1.0/28 and I send an icmp echo request to the broadcast address of the C-net (so NOT to 192.1.1.15) the 2.1.7 stack does send an echo reply but the 2.2 stack does not. So an all-subnets directed broadcast seems to be ignored on 2.2 stacks...I think this broken, yet fail to see where it was broken. -Guido
