My FreeBSD 10.2 Server has several network interfaces: ath0 bge0 wlan0 vlan2 bridge2 So what you call a VAP is actually expressed by wlan0, which is a virtual interface stacked on a physical interface, namely ath0 in this case. vlan2 is a different interface, but also virtual and stacked on bge0. Its purpose is to have a tagged network. Several vlan2 interfaces might be combined to a network by switches, that understand vlan and are physically connected to bge0. This enables several networks running through the same switches. Is this correct? vlan cannot be directly stacked onto ath0, since this would not make sense. The bridge2 glues all together and ensures that the vlan2 network is extended to a wireless endpoint. Is this correct? I'm not sure what to do with the info provided by your recommendation to have a look to edge / stp. man ifconfig => check for edge / stp What is this looping about? I also don't understand how you get your bridges working, if you do not assign IP addresses. The info you gave at point 3) is a bit overwhelming. I just picked the following: `` ... where a push the configs from the router to the ap’s....'' ``.. - ip addresses ''. So, do I understand correctly that you push the IP addresses to the APs at a later stage. -- Met vriendelijke groeten, With kind regards, Mit freundlichen Gruessen, De jrus wah, Will ************************************* W.K.
