I can't find an answer to my question asking if you have a VLAN capable switch. If you don't have a VLAN capable switch, then you have to configure your ATA to VLAN tag its interface if you are expecting it to work on VLAN 11. I have no idea if that configuration is possible.
Like i said in an earlier post:
Is the switch correctly configured? it isn't a switch with vlan support, just a normal switch. The only reason why i want to set it up with vlans is that the ip management is easier for me, and within a few months i want to set up a switch with vlan support.
Well … i tought that it was possible like i did it. So the only solution to make sure that i can create a new ip range for disks, servers, voip, ... stuff is buy a switch with vlan support, add a new nic for it (not possible) or set pfsense as 10.0.0.1/8. Bummer :-)
