vlan - pls help

[ann kok]

Hi all

Thank you for your help and info
the url is useful and same as what I did

Any help is much appreciated:

I used the tcpdump in the freebsd box
the freebox  192.168.1.6 is receiving the linux box 
192.168.1.5

but why they can't ping each other!

in freebsd box. ping 192.168.1.5
PING 192.168.1.5 (192.168.1.5): 56 data bytes
ping: sendto: Host is down
ping: sendto: Host is down

but itself is fine 
ping 192.168.1.6
PING 192.168.1.6 (192.168.1.6): 56 data bytes
64 bytes from 192.168.1.6: icmp_seq=0 ttl=64
time=0.019 ms

For the mac address of all vlans, it should be same as
the parant interface. 
but I am new for it. Sorry


 

tcpdump -ei em1
tcpdump: WARNING: em1: no IPv4 address assigned
