Hi Stefan, hi all,

I am not using vlans @home. I don't know where this VLAN ID comes from.

Ihis is what my tcpdump looks like. 10.1.2.254 is my router-box, 
connected to the internet, my iscsi-target-box is doing packet 
forwarding between workstation-net (192.168.2.x) and wlan/ internet 
(10.1.2.x).

Regards,
  Michael
