I tried watching "systat vmstat" during a ping -f and it showed nothing about et interfaces. So I forced the arp address on the other PC to be sure packets would be sent to the good mac (since arp replies did not even come). This resulted in the exact same behaviour, nothing in systat. Packets seems to go to the interface tough as the network light on et interfaces did light on continuously during my ping -f (and 1 each second during a normal ping). Best Regards
