I defined several IP-addresses with ifconfig vx0 inet 194.231.79.60 netmask 0xffffffc0 alias route add 194.231.79.60 localhost Now, when I ping this address from another network every ip-packet get duplicated: PING 194.231.79.60 (194.231.79.60): 56 data bytes 64 bytes from 194.231.79.60: icmp_seq=0 ttl=251 time=59.921 ms 64 bytes from 194.231.79.60: icmp_seq=0 ttl=251 time=69.929 ms (DUP!) 64 bytes from 194.231.79.60: icmp_seq=1 ttl=251 time=60.104 ms 64 bytes from 194.231.79.60: icmp_seq=1 ttl=251 time=70.113 ms (DUP!) 64 bytes from 194.231.79.60: icmp_seq=2 ttl=251 time=60.108 ms 64 bytes from 194.231.79.60: icmp_seq=2 ttl=251 time=70.071 ms (DUP!) 64 bytes from 194.231.79.60: icmp_seq=3 ttl=251 time=50.142 ms 64 bytes from 194.231.79.60: icmp_seq=3 ttl=251 time=60.133 ms (DUP!) ^C --- 194.231.79.60 ping statistics --- 4 packets transmitted, 4 packets received, +4 duplicates, 0% packet loss round-trip min/avg/max = 50.142/62.565/70.113 ms # There are no DUPs when pinging from within the same net. I did not have this problem with FreeBSD 2.1.5 nor with 3.0 and a NE2000 clone. Could it be a bug in the vx0 driver or did I misconfigure something?
