Hi Piccalo, I am afraid, there would be a local routing issue in your server. E.g., suppose you have two network interface cards in your machines, both belonging to the same subnet. The IP stack uses only one of them. That means, you need to have the vlan interfaces in separate subnets. regards jojan -----Original Message----- From: liam sharp [mailto:piccalo_clark@xxxxxxxxxxx] Sent: Friday, October 08, 2004 7:35 PM To: Linux 802.1Q VLAN Subject: RE: [VLAN] Linux bridge+vlan+tagging Hi Vishwas, Thanks very much for your reply. I've studied the document you refered to. The problem I have is more implementation specfic. If the gateway is going to see the traffic from all the Vlans, my understanding is it has to be plugged into a trunk port ? (A port that see's all the traffic, the ethernet frames encapsulated in their respective Vlan tags). I know how to use vconfig so I can see each vlan. But I want each vlan on the same network. It think what I want to do is remove the vlan tags before the traffic is passed up to the ip layer, and when response traffic is generated to encapsulate the ethernet frames back into vlan tags ? Does this sound appropriate ? Again, any input would be very much appreciated !
