	~~Diese IP-Liste ist obsolet - eingetragen zu diesem Stichdatum waren:~~

	* 185.194.20.2 -> wehr24 (pocki)
	* 185.194.20.3 -> bahnstr (stefan)

	* 185.194.20.43 -> vkm
	* 185.194.20.53 -> rai38 (wolfgang)

	Da pro Node im Redeemer nur eine 4in6-IP vergeben werden kann, hier weitere IPs die in Verwendung sind, wenn auf einem Node mehrere Devices existieren, die jeweils eine 4in6-IP bekommen sollen. Vermutlich wäre es besser dafür eine Möglichkeit im Redeemer zu schaffen oder anderenfalls zumindest einen Adressbereich zu haben, der nicht über den Redeemer verwaltet wird.

	Your ~~Funkfeuer~~ interfaces should be set to static IP with the nodes IPv4 address on the interface ~~(either the same IPv4 on all interfaces or if this still results in link flapping then a different IPv4 address per interface)~~.

Your FunkFeuer interfaces should be set to static IP with the nodes IPv4 address on the interface.
			For IPv6 the automatically assigned link local address is enough as long as you set up the node's IPv6 address on the loopback interface correctly.
	~~Depending on your LAN network, you might want to disable the DHCP server on the LAN interface that is enabled by default on OpenWrt~~.

	~~As for Management network I usually recommend to use one VLAN per Funkfeuer interface and have one of each VLAN tagged on the Funkfeuer interface.~~		Disable the DHCP server on the LAN interface that is enabled by default on OpenWrt.
	~~Due to limitations in~~ the ~~switching hardware~~ on ~~most routers it has to be a different VLAN ID for every port.~~
	~~As management network I generally recommend having~~ the LAN ~~network untagged on all ports. This makes it easy to connect and set up new Wifi hardware (as their management network usually~~ is ~~untagged on the ethernet interface) and makes debugging on the roof a lot easier (just plug in your laptop into a free ethernet port without any special VLAN config~~ on ~~the laptop)~~.

	~~DLEP for OLSRv2 (getting layer 2 connection information from the Wifi hardware to the OLSRv2 daemon) is currently broken in OLSRDv2 but once~~ it is ~~working you'll want a second~~ tagged ~~VLAN interface~~ on ~~every ethernet port a Wifi device is connected to. The protocol can be set~~ to ~~"unmanaged" (it still assigns an IPv6 link local address which is enough for DLEP)~~.		For Management network it is recommended to use VLAN 1100 tagged on the interfaces to antennas.
