2014-Mar-18 Currently has X-Wrt software installed on it.
Overview
This page is about RB532A. is a surplus piece of hardware that worked for a time as a firewall at work, then as an openvpn server at my house.
See also Mikrotik RouterBoard RB411
Official documentation can be found at http://www.routerboard.com/rb500.html A local copy of the user guide is here: File:RouterBoard500 userguide.pdf
Command line access: serial console 115200 8N1 (usually from Roaring using minicom) or ssh
Web interface: http://10.127.32.1/ or https://routerboard/ or from outside the lan at https://alseageo.dyndns.biz/
KAMIKAZE with X-Wrt Extensions 8.09
Web management console Webif2
Board type: 532A
Serial number: 16C901CD44DB
Firmware version: 2.10
CPU frequency: 399 MHz
Memory size: 64 MB
eth1 MAC address: 00:0C:42:10:1C:6C
eth2 MAC address: 00:0C:42:10:1C:6D
eth3 MAC address: 00:0C:42:10:1C:6E
To-do
- QoS
- dmz - allow OpenVpn access ?
- OpenVPN - switch over from Kilchis?
- Scheduled QoS control?
- Crow? or similar
- WoL
I tried to override the WAN interface default MAC address so that Comcast would not change our public IP address but for some reason that feature in the GUI fails.
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.
Available distributions
OpenWRT and X-WRT are installed.
Support for it in OpenWrt seems to be pretty good, they have the latest releases prebuilt for the RouterBoard. 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/
I no longer put all 4 screws into the MicroTik case. :-)
Install took 10 minutes including opening up the case. OpenWrtDocs/Hardware/Mikrotik/RB532
DD-WRT 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
Miscellaneous configuration notes
Password
Root password set from the console port command line using "passwd". Set to the usual root password.
Network
I hand edited this config file to create three networks. Should be possible to do it all from the GUI but maybe that did not work back when I originally set it up.
The WAN interface has its MAC address overridden so that it uses the same MAC as the old D-Link router. That way switching back and forth between the RouterBoard and the D-Link should not cause our Comcast DHCP address to change.
Note this did not work -- maybe I have the syntax wrong in the file? I had to go into the command line and override the setting like this
ifconfig eth0 down ifconfig eth0 hw ether '00:0D:88:5F:E8:90'
It loses the settings when I reboot, so I am ignoring it for the moment. We have a new IP address, darn.

Route command
Adding a default route so that you can get the webif stuff running initially; you need to add some packages.
route add default gw 192.168.123.254
Packages added
After getting webif running I use it to make these package additions/deletions.
etherwake ntpd openvpn tcpdump wol nbd's QoS scripts
Packages removed
ppp ppp-mod-pppoe
DHCP
We provide DHCP only to the DMZ zone.
/etc/config/dhcp
config dhcp
option interface lan
option ignore 1
config dhcp
option interface dmz
option start 190
option limit 199
option leasetime 1h
config dhcp
option interface wan
option ignore 1
DNS
dnsmasq is installed but I am not currently using it.
I put this in /etc/resolv.conf so that it will use Kilchis to resolve names.
nameserver 10.127.32.27 domain alseageo.com
Dyndns
There is a DynDNS tab under Network in the GUI. You can install and configure dyndns service.
Another way to do this is via ddclient on Kilchis, which is currently disabled. It used to run once per hour from /etc/cron.hourly/ddclient.
The config file for dyndns on the routerboard is /etc/config/updatedd:
config 'updatedd'
option 'update' '0'
option 'service' 'changeip'
option 'username' 'alseageo'
option 'password' 'ice9viva'

NTP
Set timezone to US/Pacific Set servers to {0,1,2}.pool.ntp.org
NOTE: The standard WebIF ntp client has been removed from the GUI package manager.
I enabled the ntpd like this:
cd /etc/rc.d ln -s ../init.d/ntpd S99ntpd
All I had to change in ntp.conf was to add a rule allowing our 10.x.x.x clients.
cat ntp.conf

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
Wake-On-Lan
Installed not configured
VPN
OpenVPN
Installed package. Not configured yet.

Set up
Support for the RouterBoard in OpenWrt seems to be pretty good, they have the latest releases prebuilt for the RouterBoard.
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.
Reflashing with OpenWrt X-Wrt
http://wiki.openwrt.org/OpenWrtDocs/Hardware/Mikrotik/RB532
The simplest way is to 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.
Use the 'dd' command under Linux or Macintosh to copy the image to the CF card. 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.
On my Macintosh with a USB card reader the command is almost the same, Macs are pretty cool actually.
sudo dd if=openwrt-rb532-jffs2-12k.bin of=/dev/disk1

NTP
Set timezone to US/Pacific Set servers to {0,1,2}.pool.ntp.org
Add this line to ntp.conf
restrict 192.168.123.0 mask 255.255.255.0
Add link to /etc/rc.d so that ntpd will start, you can do this in webIf services page.
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.
SSL
Installed MatrixSSL so that we can connect to router using a secure connection.
Syslog
Set to log to Bellman.
Wake-On-Lan
Installed not configured yet
VPN
OpenVPN
This end will connect with AGI's and keep the connection nailed up. I suppose I could also allow access back in from the world at large but that is not my primary objective.
So I do the usual - copy the config files from the AGI server and then start it up.
Phone server options
These are available as packages for OpenWrt
- Asterisk 1.4, 1.6 - a pain to debug configurations
- FreeSwitch - B2BUA/media gateway
- kamailio
- OpenSER 1.0.1-1 - Outdated version, it's called OpenSIPS now
- OpenSIPS 1.5.3-1 - SIP Proxy
FreeSwitch is divided into many packages. I am installing it on the system that I have been running Asterisk on, so that I can try it out on a real computer.
