Reflashing
http://wiki.openwrt.org/OpenWrtDocs/Hardware/Mikrotik/RB532
The simplest way is to simply download the CF image file from http://downloads.x-wrt.org/xwrt/kamikaze/ and then use 'dd' to copy it to a CF card, then put the CF into the RouterBoard and off you go.
Get the 128k image. The 128k refers to the block size in the filesystem and it's good for CF cards.
The healthy way to copy binary images to CF is 'dd' under Linux. Cygwin includes a 'dd' command so if you are burdened with Windows you can still use dd. I did not get it working and ended up simply usng Linux. YMMV http://www.groupsrv.com/linux/about17777.html
dd if=/dev/sdb of=backupimage.bin dd if=openwrt-rb532-jffs2-128k.bin of=/dev/sdb
The backup image is 256MB because that's the device size. Wastes some disk space but then again I delete it as soon as the RouterBoard is up and running again.

AGI
In our internal DNS, it's called OpenWRT and can be reached via ssh or https://openwrt/ or from outside the lan at https://alseageo.dyndns.biz/
Support for it in OpenWrt seems to be pretty good, they have the latest releases prebuilt for it. I used instructions in this page to get it loaded.
I installed KAMIKAZE (7.09) then later I found out about X-WRT and installed their version from http://downloads.x-wrt.org/xwrt/kamikaze/7.09/
I no longer put all 4 screws into the MicroTik case. :-)
Install took 10 minutes including opening up the case. OpenWrtDocs/Hardware/Mikrotik/RB532
Support in dd-wrt is not good. There is an old beta.
CF layout
Kamikaze fits in a 16MB flash so any old CF card will do for booting.
Ethernet ports
There are three, the one to the left of the serial port is eth0 To the right are eth1 and eth2
By default in Kamikaze eth0 is in DHCP so it would make a good WAN port
MAC numbers
- eth0 00:0c:42:10:1c:6c
- eth1 00:0c:42:10:1c:6d
- eth2 00:0c:42:10:1c:6e
Miscellaneous onfiguration
Password
Root password set from the console port command line using "passwd". Set to the usual root password.

Dyndns
Installed changeip client.
Firewall
Not set up yet.
NTP
Set timezone to US/Pacific Installed client.
QoS
Install but not configured yet. I'd like to use this to control bandwidth used for offsite backups. I want full utilization at night and 200 Kbps during business hours. A way to switch it down to a low bandwidth manually would be good.
SNMP
Installed but not configured yet. Could be set to log to cacti on Kilchis
SSL
Installed MatrixSSL so that we can connect to router using a secure connection.
Syslog
Set to log to Kilchis. 10.127.32.27/514 Do a MARK every 20 minutes.
Wake-On-Lan
12/22/07 Not available yet in X-Wrt. This would allow us to power on Desktop machines remotely.
VPN
L2TPns
Have not looked into this one yet. Package is installed.
OpenVPN
