Is there a way to incorporate VLAN's on wireless links with Nsterme ?
For VLAN's to work link has to be in AP-WDS-Slave mode, on the other side Nstreme won't work with WDS-Slave. Nstreme requires AP-Station config in which VLAN's won't work.
Any ideas ?

you can try to set vlan on eth, not on wlan card/

vlan--------------------------------------------------------------------------vlan
lan-eth/RB or PC/wlancard --any kind of link--wlan card/RB or PC/eth-lan
