My switch cannot be configured untagged and tagged on the same vlan on the
same port. (but tagged on one vlan and untagged on another vlan on the same
port)
When I talked about configuration with eth0 and eth0.3, it was with adequat
switch configuration :

------------
port switch : tagged vlan3, tagged vlan2, tagged vlan1
routeur on vlan 3, interface eth0.3
users on vlan 2, interface eth0.2
users on vlan 1, interface eth0.1
eth0 : ifconfig 0.0.0.0 up
ping works.
With same configuration on my data serveur : samba and netatalk works fine
to users
--->Squid deserve request with maybe 10 minutes delay.

---------
port switch : untagged vlan3, tagged vlan2, tagged vlan1
routeur on vlan 3, interface eth0
users on vlan 2, interface eth0.2
users on vlan 1, interface eth0.1
ping works.
With same configuration on my data serveur : samba and netatalk works fine
to users
--->Squid works fine except weird issues with some websites (hotmail,
yahoo!mail, ebay...)

---------
port switch1 : untagged vlan3
port switch2 : untagged vlan2
port switch3 : untagged vlan1
routeur on vlan 3, interface eth0
users on vlan 2, interface eth1
users on vlan 3, interface eth2
ping works.
With same configuration on my data serveur : samba and netatalk works fine
to users
--->Squid works fine

No idea the reason...
