That is a capital I (eye) in the ping command by the way...

Ok, let me make sure I have this right. So if you have a virtual
machine with ip 10.30.104.X, with its adapter in the appropriate
vsiwtch in ESX to be on vlan 104, you can ping the 10.30.104.1 ip,
but the 10.30.104.1 ip can not ping the same host that just pinged
it? That sounds like a firewall issue at the host level. If you can
ping one from the other, then there is obviously two-way traffic
established, so something has to be blocking the packets originating
from the vyatta box. Either that or the vyatta box is not using the
appropriate source address and the return traffic is not being
routed properly. Try this from the unix shell on your vyatta:
ping -I 10.30.104.1 10.30.104.X
where X is the ip of a box that can ping the vyatta box. Let me know
what happens there...
I don't know how much you know about swithing, but the native vlan
just means that all untagged traffic into the interface is marked as
belonging to the native vlan, in this case 101. Since you have the
vlan101 ip space untagged on eth0 on your vyatta box, that is why
you can ping it from the switch when you add 101 as the native vlan
to the trunk.

Hello,
I attached the config of the two switches in the message.
Note tha the switches can't ping the vyatta, and vyatta can't ping
the switches ( vyatta and switches are in the same vlan 101). But
when i change the native vlan of the interface gi0/43 (Trunk
between sw1 and vyatta ) to 101 using the command "switchport trunk
native vlan 101", i can ping sw1 and sw2 from vyatta , and switches
can ping vyatta.
Note also that each vms can ping all the interfaces of vyatta
( eth0 and all vif); but Vyatta can't ping vms .
VMs on the same vlan can communicate
The config of vyatta is very simple, because my goal is to route
two vlans : route vlan 104 and 106 in first time:
ethernet eth0{
description "To_switch1"
hw-id: .......
address 10.30.101.254 {prefix-length:24}
vif 104{
description:"Vlan 104"
address 10.30.104.1 {prefix-length:24}
}
vif 106{
description:"Vlan 106"
address 10.30.106.1 {prefix-length:24}
}
}
ps: Virtual switches of ESX tag Virtual machines packets with the
appropiate vlan ID.
Thanks a lot for your help.
