vlan + debian

Hi,


I have a Linux (Debian) that has a native support for configure vlan on 
interfaces file.

So I've configured vlan and the interface is up as shown bellow.

vlan2      Encapsulamento do Link: Ethernet  Endereço de HW 
00:11:D8:AA:94:D9
           inet end.: 135.153.2.1  Bcast:135.153.255.255  
Masc:255.255.255.0
          UP BROADCASTRUNNING MULTICAST  MTU:1500  Métrica:1
          RX packets:183 errors:0 dropped:0 overruns:0 frame:0
          TX packets:4 errors:0 dropped:0 overruns:0 carrier:0
          colisões:0 txqueuelen:0
          RX bytes:22470 (21.9 KiB)  TX bytes:1384 (1.3 KiB)

  I can get IP from my dhcp  server trought the switch tagged port that 
the server is attached to, but I'm unable to ping the server's 
interface... (The host is plugged in another  untagged port)

I've read that some NICs doesn't work with 802.1q frames...  I don't 
know that's the problem... but in case it's the problem I could not get 
the ip from dhcp server.... right!?

I'm using the uggly rtl8139 to test..
Any ideia about what the problem,..?

Regards

Fabiano
