== Initial config ==

Since the installation of the Wireless Antwerp access-point on the Belgacom tower we now have line of sight to this wireless network.

To make the connection we have a NanoStation M5. This is installed in the far corner of the slightly higher part of the roof of our building. Power is supplied through POE. The POE cable must be connected to the port on the NanoStation labelled main. The NanoStation can be configured through a web-interface.

<pre>
The link to Wireless Antwerpen on the roof is now live. We have a policy
routing setup where addresses in 10.97.212.0/24 range automatically go out
via the WA link, and everything else via the regular Dommel link. You can
reach machines in the WA internal network from the regular LAN range,
however this still needs a bit of tuning.

Addresses in that new range are not yet given out by the DHCP server, but
they will be as soon as we get this set up. The idea is that we'll put
"known" MAC addresses (see Pamela) in the Dommel range, and visitors get on
the WO link. So we'll also be doing a "guest" WIFI network for this. Of
course, you can give yourself an IP address in this range (.1 is the soekris).

The dn42 link is down. The quagga on the soekris cannot handle BGP in more
than one AS, and both dn42 and WA need us to use specific ASNs. If anyone
still needs dn42, a fix will need to be found.

It's all a bit much for the soekris... we really need to replace it with
something that has 1) more CPU, and 2) more ports. We'll need a minimum of 4
ethernet ports. This will require some investment though.
